Question

A desiccator is an air-tight glass vessel with a suitable drying agent, ________ placed at the bottom of the vessel.

Answer 1

Desiccator:-

• A desiccator is a bowl of thick glass with a lid and also there is a perforated ceramic disc that separates it into two partitions.
• The drying agent which is the desiccator is placed beneath the silica disc and the chemical that needs to be dried or kept in a dry condition is placed above the silica disc.
• These desiccators are basically used to keep a low humidity in the atmosphere with the help of these drying agents.
• The lower compartment contains a lump of silica gel, freshly calcined quicklime, Drierite, or anhydrous calcium chloride$\left({\mathrm{CaCl}}_2\right)$(which is not as effective).
• These chemicals absorb the water vapour and thus act as drying agents.
• These desiccators should not be left out open, except for the transfer of the sample in and out of it.

Therefore, a desiccator is an air-tight glass vessel with a suitable drying agent, anhydrous calcium chloride$\left({\mathrm{CaCl}}_2\right)$ placed at the bottom of the vessel
