Solution

## 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
