Using fractional recrystallization.
Basically the purpose of desiccators is storage of samples free from moisture . so Calcium chloride is a hygroscopic (capable of absorbing moisture) ,so we are using this in desiccators. and it is sometimes also called a drying agent.
The gram atomic mass of calcium is 40.08, the formula of anhydrous calcium chloride is CaCl2, showing that each formula unit contains one calcium atom, and the gram formula mass of anhydrous calcium chloride is 110.99. Therefore, 19050.9 grams of calcium chloride contains 19050.9(40.08/110.99) or 6.880 X 103 grams, to the justified* number of significant digits. ____________________________________________ *There may well be tables of gram atomic and gram formula masses more modern than the one I am using that would allow for more significant digits in the answer.
Yes. Ammonium salts such as ammonium chloride will react with a strong base to yield ammonia.
Mix dilute hydrochloric acid with calcium carbonate to obtain a calcium chloride solution; then add sodium sulphate solution to the calcium chloride solution to obtain calcium sulphate precipitate.
Using fractional recrystallization.
In 1861, canners began adding calcium chloride to the water in which they cooked their closed cans
Salt is made up of calcium and chloride. Calcium is a necessary ingredient to a good diet.
magnesium sulphate, calcium chloride and ferric chloride are added to provided optimum environment and phosphate buffer is added to slow down the rate of death of microbes.

Laboratory preparation of ammonia or NH3 requires using ammonium chloride and calcium hydroxide. The reaction equation is 2NH4Cl plus CaOH2 gives the products 2NH3 plus CaCl2 plus 2H2O. The ammonium chloride and calcium hydroxide are heated for this reaction.
Using Downs process, by the electrolysis of molten sodium chloride. This is done in a Downs Cell in which the NaCl is mixed with calcium chloride to lower the melting point below 700 °C. As calcium is less electropositive than sodium, no calcium will be deposited at the cathode. This method is less expensive than the previous Castner process of electrolyzing sodium hydroxide.
