Question

Q.9 Give reasons-
a) Silver chloride is stored in dark coloured bottles.
b) Copper vesselloses shine when exposed to air
c) Iron is places copper from copper sulphate solution​

Answer 1

Ans for a) - 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.

Ans for b) - A copper vessel reacts with oxygen present in air when exposed to it , they forms copper oxide which , in turn , is a black coating over the vessel and makes the vessel to lose its shine .

Ans for c) - Iron metal is more reactive than copper. Therefore, it can displace copper from copper sulphate (CuSO4) solution. Cu is less reactive than iron, therefore, cannot replace iron from iron sulphate (FeSO4).
