Question

What happens when the gas evolved at anode is passed through dry slaked lime? Write the chemical equation involved. Write two uses of the product
formed.​

Answer 1

Answer:

Carbon dioxide turns lime water milky when passed through it because of formation of calcium carbonate.On the electrolysis of brine, chlorine gas is deposited over anode which gives calcium oxychloride (Bleaching powder) on passing over slaked lime. The bleaching powder is used in disinfecting the drinking water.

Explanation:

When chlorine is passed over dry slaked lime, bleaching powder will form. equation ---: Ca(OH)2 + Cl2 ---> CaOCl2 + H2O. properties --: it is used as an oxidising agent in many chemical industries.
