00:00:07.390 --> 00:00:10.000 Our topic for today is simple distillation. 00:01:48.800 --> 00:01:59.100 The process of heating a liquid mixture to form a vapor and then cooling that vapor to obtain a liquid called simple distillation. 00:01:59.100 --> 00:02:04.000 Distillation is used to purify the liquid by separating the components of the liquid mixture. 00:02:13.100 --> 00:02:18.000 Let's do an activity to understand simple distillation. 00:02:22.840 --> 00:02:28.000 Take a mixture of acetone and water in the distillation bottle. 00:02:42.640 --> 00:02:44.100 Put the thermometer in it. 00:02:58.170 --> 00:03:00.000 Connect the vial to the water capacitor. 00:03:10.209 --> 00:03:15.000 The condenser has cold water running through a jacket to maintain a cool temperature. 00:03:19.349 --> 00:03:21.650 Keep a cup in the condenser outlet. 00:03:38.000 --> 00:03:43.000 Heat the mixture, while keeping an eye on the thermometer. 00:03:43.000 --> 00:03:49.000 When the temperature reaches 56 ° C, acetone begins to vaporize. 00:04:05.379 --> 00:04:08.000 These fumes condense in the water condenser. 00:04:27.850 --> 00:04:31.000 Intensive acetone is collected in a cup. 00:04:34.540 --> 00:04:46.000 When all acetone evaporates, water is left in the flask, and acetone is collected in a cup. 00:04:49.190 --> 00:04:54.000 In this way, acetone and water are separated by simple distillation. 00:05:12.230 --> 00:05:17.660 The boiling point of water is 100 ° C. 00:05:17.660 --> 00:05:20.890 The boiling point of acetone is 56 ° C. 00:05:20.890 --> 00:05:32.200 There is also a sufficient difference between the boiling points, these components can be separated by simple distillation. 00:05:32.260 --> 00:05:42.500 Simple distillation does not work properly when the difference between 2 boiling points is less than 25 ° C. 00:05:42.500 --> 00:05:49.160 This is because the ingredients do not get separated and purified completely. 00:05:49.160 --> 00:05:57.180 If we repeat this process several times, we will be able to separate these components 2. 00:05:57.180 --> 00:06:06.500 However, since this is a very time consuming, it uses a special type of distillation called fractional distillation.
