Describe how you would prepare a pure dry sample of calcium chloride in the laboratory mention 5 ways?
1. By first obtaining a solid sample of calcium chloride from a chemical supplier or by synthesizing it through a chemical reaction.
2. By crushing the solid calcium chloride sample into a fine powder to increase the surface area for drying.
3. By placing the crushed calcium chloride sample in a desiccator with a drying agent such as silica gel or anhydrous calcium chloride to remove any residual moisture.
4. By heating the sample in a drying oven at a specific temperature to further remove any remaining moisture content.
5. By transferring the dried calcium chloride sample into a labeled, airtight container for storage and future use.
