Answer 2

Answer:

option  d. Desiccation​

Explanation:

Desiccation is a technique for completely removing mechanically admixed water from materials.

• The apparatus that is utilised in the laboratory is called a laboratory scale apparatus. For this, a desiccator is utilised.
• It's a glass vessel with a lid. Concentrated sulphuric acid, phosphorous trioxide, phosphorous pentaoxide, anhydrous calcium chloride, anhydrous lime, or dried silica gel are added at the bottom of the desiccators.
• The dried material is placed on the china dish, which is held in place by the perforated plate's projected arms. The desiccator is sealed with a floor-edged cover that is usually oiled to guarantee an airtight seal.
• Some desiccators have a ground glass stopcock at the outlet that can be connected to a vacuum pump to remove the air.
