Question

The average volume of the acid was mixed with 25cm3 of pottasium carbonate solution to obtain potassium chloride solution.

Describe how you would obtain crystals of pottasium chloride from the solution.

Answer 1

To obtain crystals of potassium chloride from the solution, you can follow the following steps:

1. Heat the solution to evaporate some of the water and concentrate the solution.

2. Continue heating the solution until crystals start to form at the bottom of the container.

3. Remove the container from heat and allow it to cool down to room temperature.

4. Once the solution has cooled, you can use a filter paper and funnel to filter out the crystals from the remaining solution.

5. Wash the crystals with a small amount of cold distilled water to remove any impurities.

6. Dry the crystals by placing them on a watch glass or filter paper in a warm place until all the water has evaporated.

By following these steps, you should be able to obtain pure crystals of potassium chloride from the solution.
