Of the following the commonly used as a laboratory desiccator is :
Open in App
Solution
The correct option is C CaCl2
Desiccators are used to dry chemicals before they are used in chemical reactions. This makes them important for scientists who use chemical reactions in laboratories.
Desiccators are usually sealed so that outside air cannot enter the chamber. In some cases, desiccators may also be fitted with a vacuum hose in order to remove excess air from the inside of the chamber. A desiccant, or drying material, is usually added to the desiccator to absorb water vapor whenever the desiccator is opened.Calcium chloride (a salt) and silica gel (a non-reactive solid) are two typical desiccants that are used routinely. The desiccants ensure that water vapor is absorbed before it reaches the reactants.
Hence option B is correct.
