Question:
A metal X is obtained from its chloride salt by exposure to sunlight.
(a) In which section of the reactivity series of metals- top, middle or bottom, is
it likely to be placed? Justify your answer.
(b) Identify the type of reaction the chloride salt of metal X undergoes on
exposure to sunlight.
Answer:
1) Metal X is Ag
2AgCl(s) → 2Ag(s) + Cl2(g) (In the presence of sunlight)
2) Ag is placed in the bottom of reactivity series since it is not very reactive in nature.
3) Decomposition reaction (to be very precise it is photochemical decomposition)
