all right so in this experiment I want
00:00:04.070 00:00:04.080 to test what's inside all these
00:00:05.660 00:00:05.670 different dipped capacitors seen a lot
00:00:09.650 00:00:09.660 of people label in different ones as
00:00:11.299 00:00:11.309 tantalum capacitors and I didn't think
00:00:13.459 00:00:13.469 they were actually tantalum so I'm
00:00:15.799 00:00:15.809 taking them apart to try to figure out
00:00:18.080 00:00:18.090 once in time so I took one of those
00:00:20.510 00:00:20.520 little one and I cracked it open and it
00:00:25.810 00:00:25.820 appears to be a little copper coil
00:00:28.160 00:00:28.170 surrounded in iron so those are
00:00:32.330 00:00:32.340 obviously out it's no precious metal
00:00:34.880 00:00:34.890 value to them so I got these standard
00:00:37.340 00:00:37.350 green ones which are on a lot of boards
00:00:40.760 00:00:40.770 I tried to speed up this video to make
00:00:43.700 00:00:43.710 it faster so you don't have to watch me
00:00:47.150 00:00:47.160 fumble through trying to get a nice
00:00:49.330 00:00:49.340 sample to test
00:01:01.029 00:01:01.039 so I'm just trying to cut these open
00:01:30.630 00:01:30.640 so there are got a little piece of metal
00:01:32.370 00:01:32.380 from me inside of those green capacitors
00:01:35.240 00:01:35.250 so I'm just going to add a little bit of
00:01:38.910 00:01:38.920 hydrochloric acid and see what happens
00:01:40.920 00:01:40.930 because it looks a lot like a luminol so
00:01:44.700 00:01:44.710 you can see that violent reaction going
00:01:46.620 00:01:46.630 that's obviously aluminum in those
00:01:49.080 00:01:49.090 capacitors so I take one that's a little
00:01:58.370 00:01:58.380 different same color but a little
00:02:01.890 00:02:01.900 different shape just to see what what's
00:02:05.640 00:02:05.650 in it cut off a little piece put in tied
00:02:08.729 00:02:08.739 to horik acid again so this one is
00:02:15.170 00:02:15.180 harder to see I didn't have enough acid
00:02:17.880 00:02:17.890 so I add some more here in a second
00:02:22.070 00:02:22.080 there we go
00:02:23.490 00:02:23.500 now you can see the violent reaction so
00:02:25.830 00:02:25.840 it's kind of quick so if you want to
00:02:27.180 00:02:27.190 watch if you want to get a quick
00:02:29.400 00:02:29.410 snapshot of the reaction and just pause
00:02:31.530 00:02:31.540 it so I took all those out those are
00:02:34.370 00:02:34.380 those are out of the window for precious
00:02:39.240 00:02:39.250 metals so they're just aluminum so I had
00:02:45.300 00:02:45.310 a weird looking black one there so I
00:02:47.759 00:02:47.769 decided to cut it open and see if it
00:02:49.560 00:02:49.570 look the same and it looked the same
00:02:51.690 00:02:51.700 setting even tested now on to some
00:02:57.150 00:02:57.160 bigger star ones which are more
00:03:00.150 00:03:00.160 rectangular with the legs on the longest
00:03:03.150 00:03:03.160 ends so I unwrapped that one
00:03:09.060 00:03:09.070 it looks like aluminium again so I'm
00:03:13.050 00:03:13.060 just going to try to put some
00:03:14.100 00:03:14.110 hydrochloric acid on
00:03:31.400 00:03:31.410 so that was obviously aluminum so now I
00:03:35.600 00:03:35.610 got some other ones different color same
00:03:38.180 00:03:38.190 kind of same kind of setup so I'm just
00:03:44.630 00:03:44.640 cracking them open and I'm a little bit
00:03:48.920 00:03:48.930 off-camera I apologize today yeah that
00:03:52.520 00:03:52.530 one looks like lumen into so now I'm
00:03:54.770 00:03:54.780 just kind of basing them all off their
00:03:57.440 00:03:57.450 style if they look like they're that in
00:03:59.780 00:03:59.790 film of aluminum they most likely are so
00:04:04.850 00:04:04.860 there's another one to fill them that
00:04:06.740 00:04:06.750 was a bigger one now I'm going to these
00:04:09.290 00:04:09.300 round dipped capacitors they have a
00:04:12.740 00:04:12.750 weight they have a different style so it
00:04:17.180 00:04:17.190 appears that it's some kind of weird
00:04:20.510 00:04:20.520 ceramic coated with a metal and I
00:04:24.230 00:04:24.240 believe that metal it looks a lot like
00:04:26.480 00:04:26.490 silver so there we go I got a nice chunk
00:04:30.920 00:04:30.930 of silver silver looking metal anyway
00:04:37.190 00:04:37.200 we're going to do a test to make sure is
00:04:39.140 00:04:39.150 silver so I put it in there put in and
00:04:42.440 00:04:42.450 test you put in some dilute nitric acid
00:04:46.870 00:04:46.880 which the video was a little fast I
00:04:49.670 00:04:49.680 don't think you saw or that first test
00:04:51.950 00:04:51.960 with hydrochloric acid just to see what
00:04:54.440 00:04:54.450 happen so now I put in another piece and
00:04:57.140 00:04:57.150 now I'm going to put in dilute nitric
00:04:58.280 00:04:58.290 acid so I'm going to try to show you the
00:05:03.140 00:05:03.150 reaction so it's it's a hard to tell
00:05:08.960 00:05:08.970 because this pasture was blue but the
00:05:10.850 00:05:10.860 solution it's slowly turning a greenish
00:05:14.390 00:05:14.400 blue
00:05:21.340 00:05:21.350 so that one's hard to tell so I left
00:05:30.770 00:05:30.780 that one up and tested it too quickly so
00:05:35.450 00:05:35.460 now I'm going to try different these
00:05:38.710 00:05:38.720 same tests it's just hard to get a piece
00:05:43.310 00:05:43.320 that's not covered in ceramic because I
00:05:46.190 00:05:46.200 believe the ceramic consumes the acid as
00:05:48.890 00:05:48.900 well so here's the big red one which is
00:05:52.400 00:05:52.410 the same construction just bigger size
00:05:55.010 00:05:55.020 and there's some nice metal show in
00:05:58.520 00:05:58.530 there so I'm going to break off piece
00:06:02.120 00:06:02.130 and throw it in there so since this one
00:06:08.420 00:06:08.430 person's last one I done too quick I'm
00:06:11.540 00:06:11.550 going to set this one to the side and
00:06:13.660 00:06:13.670 move on and test the next one at the
00:06:17.480 00:06:17.490 same time so there you I'll show you a
00:06:25.250 00:06:25.260 that's in there to test so here's a
00:06:28.370 00:06:28.380 little three-legged strange-looking
00:06:32.180 00:06:32.190 I don't even know what this is at this
00:06:35.780 00:06:35.790 point um I cut it open it looks like a
00:06:38.810 00:06:38.820 little piece of iron so test fit on that
00:06:41.750 00:06:41.760 little magnet on my wire cutters and it
00:06:44.840 00:06:44.850 stuck strongly so I'm assuming it I
00:06:51.160 00:06:51.170 can't remember what they're called
00:06:55.090 00:06:55.100 my label is hell on the circuit boards
00:06:59.890 00:06:59.900 anyway I'll probably or oh it's a
00:07:03.110 00:07:03.120 inductor I believe it's an inductor so I
00:07:08.350 00:07:08.360 put that one out and that one's out so
00:07:11.270 00:07:11.280 now I moved on to the brown looking
00:07:13.780 00:07:13.790 round ones brown ceramic rambling and I
00:07:19.120 00:07:19.130 put some nitric acid in that one I just
00:07:21.830 00:07:21.840 went ahead and gift the hydrochloric
00:07:24.320 00:07:24.330 acid because I believe these are very
00:07:27.710 00:07:27.720 similar to the blue ones
00:07:32.920 00:07:32.930 so right here I test it there you go
00:07:36.730 00:07:36.740 there you can see I put in some sodium
00:07:39.820 00:07:39.830 chloride solution and instantly
00:07:41.650 00:07:41.660 precipitated silver chloride so I put
00:07:44.560 00:07:44.570 that in my silver chloride collection
00:07:46.980 00:07:46.990 I'm going to collect this and refine it
00:07:49.510 00:07:49.520 later you got a little bit on my rock in
00:07:52.719 00:07:52.729 the excess nitric acid ate it up a
00:07:56.499 00:07:56.509 little bit so right here is where my
00:07:59.590 00:07:59.600 camera cut and so I had to redo the test
00:08:04.210 00:08:04.220 that shows you the brown ceramic one and
00:08:06.310 00:08:06.320 I also redid the one with the coated
00:08:10.930 00:08:10.940 colored ceramic so there you go you can
00:08:20.980 00:08:20.990 there's that one again I just did that
00:08:23.230 00:08:23.240 when it was positive and it's positive
00:08:25.089 00:08:25.099 again so that one has those coated round
00:08:30.520 00:08:30.530 ones have silver in them now I did this
00:08:39.329 00:08:39.339 brown round ceramic one several times
00:08:43.149 00:08:43.159 and got positive I got a strong positive
00:08:47.440 00:08:47.450 the first time which was because I used
00:08:50.320 00:08:50.330 a lot of material and then I got two
00:08:54.460 00:08:54.470 weak positive so it's actually pretty
00:08:57.370 00:08:57.380 difficult to see the reaction happening
00:09:01.000 00:09:01.010 but there's a small amount of
00:09:03.519 00:09:03.529 precipitation I'm trying to show you
00:09:06.720 00:09:06.730 it's very hard to tell because there's
00:09:10.600 00:09:10.610 not much silver in solution so anyways
00:09:15.269 00:09:15.279 what this is saying you could see all
00:09:18.160 00:09:18.170 the different types of coated capacitors
00:09:21.460 00:09:21.470 or inductors whatever you want to call
00:09:23.170 00:09:23.180 them i tested and the round ones are the
00:09:28.269 00:09:28.279 ones with the silver while the coated
00:09:31.690 00:09:31.700 round ones that are coated in the
00:09:33.190 00:09:33.200 colored plastic are the higher value of
00:09:36.820 00:09:36.830 silver compared to the brown ceramics so
00:09:41.199 00:09:41.209 here I'm just showing you the two
00:09:43.360 00:09:43.370 different types that have silver
00:09:45.380 00:09:45.390 you
