Question

Q 30. (i) Zinc liberates Hydrogen gas on reaction with dilute hydrochloric acid, whereas
copper does not, Explain. (3)
(ii) Why do we store silver chloride in dark colour bottles?​

Answer 1

Answer:

Zinc reacts with hydrochloric acid to liberate Hydrogen gas as it is more reactive than Hydrogen and hence, displace it. Copper is less reactive when compared to Hydrogen and hence cannot displace it. The same can be understood by looking at the activity series of metals.

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.
