Drierite (CaSO4) and calcium chloride are used in drying tubes to keep moisture out of reaction vessels. What properties are desirable for these agents?
Homework Answers
Calcium chloride and calcium sulphate are used in drying tubes as these are used as hygroscopic compounds means it readily absorbs water.
Anhydrous calcium chloride is a good desiccant due to drying nature CaCl2.2H2O It cannot be used to dry alcohol or ammonia as it forms addition products with them.

Sodium chloride (NaCl) is commonly used to melt ice on roads during the winter. Calcium chloride (CaCl2) is sometimes used for this purpose too. Let us compare the effectiveness of equal masses of these two compounds in lowering the freezing point of water by calculating the freezing point depression of solutions containing 230. g of each salt in 1.00 kg of water. (An advantage of CaCl2 is that it acts more quickly because it is hygroscopic, that is, it absorbs...
