Question

Which of the following is an example of a drying agent?
(A) Fused Calcium Chloride
(B) Quick lime
(C) Concentrated Sulphuric acid
(D) All of the above

Answer 1

Hint :Drying agents (also known as desiccants) are used in a variety of industries, including food, pharmaceuticals, packaging, electronics, and many others. A desiccant is a hygroscopic material that creates or maintains a dry environment around it. It is chemically stable and chemically inert in its ideal state (i.e., silica).

Complete Step By Step Answer:
Drying agents (also known as desiccants) are used in a variety of industries, including food, pharmaceuticals, packaging, electronics, and many others. A desiccant is a hygroscopic material that creates or maintains a dry environment around it. It is chemically stable and chemically inert in its ideal state (i.e., silica). Unfortunately, since the drying agent comes into close contact with the solvent and the chemical in the chemistry lab, this is not always the case. To extract trace quantities of water from an organic solution, drying agents are used.
Sulphuric acid extracts water from liquids and serves as a drying agent for gases. Owing to its strong affinity for water, it also serves as a dehydrating agent, removing chemically combined water from compounds.
Burning limestone produces calcium oxide (also known as quicklime, burnt lime, or unslaked lime). As quicklime reacts with water, it produces a lot of heat. It can also be used as a drying or neutralising agent, as well as a fertiliser lime and to make lime mortar and lime plaster.
Calcium chloride, in its anhydrous form, is a cost-effective drying agent that is important for laboratory drying processes. Drying of liquids and neutral gases are two examples. Calcium chloride has a 98 percent drying capability. It crystallises to bind the water and can be regenerated by warming.
Hence, option D is correct.
