Question

a) small amount of acid is added a water during electrolysis of water

b) whan ammonium chloride is dissolved in water in a test tube the test tube become cold

c) why dowe store silver chloride in dark bottle?​

Answer 1

Answer:

a)sulfuric acid

sulfuric acidAdding sulfuric acid to water during electrolysis increases the electric flow because it is a good electrolyte and helps in moving the electrons.

b)On dissolving ammonium chloride (NH4Cl) in water in a test tube, the test tube becomes cold as it takes heat from the surrounding water. Hence, it is an endothermic reaction.

c)Silver chloride is a light-sensitive chemical compound andit easily undergoes photolytic decomposition reaction. Silver chloride decomposes into silver and chlorine gas when exposed to sunlight. Hence Silver chloride is stored in dark-colored bottles.
