Question

Give reason
a) silver chloride is stored in dark coloured bottle.
b) copper vessel loses shine when exposed to air.
c) iron is places copper from copper sulphate solution.

Answer 1

1. 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.
2. One of the main reason why the copper vessels lose their shine when exposed to air is due to the passivization. ... At the surface of vessel, Copper atoms react with the Oxygen atoms in the air forming copper-oxide.
3. Copper cannot displace iron from iron sulphate solution. Copper is less reactive than iron. Iron is placed above the copper in reactivity series of metals.

Answer 2

Answer:

Silver chloride is a light-sensitive chemical compound and it 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.

One of the main reason why the copper vessels lose their shine when exposed to air is due to the passivization. ... At the surface of vessel, Copper atoms react with the Oxygen atoms in the air forming copper-oxide.

Copper cannot displace iron from iron sulphate solution. Copper is less reactive than iron. Iron is placed above the copper in reactivity series of metals.
