Question

A metal X, used for galvanisation, reacts with oxygen to give white coloured amphoteric oxide Y, which further

reacts with sodium hydroxide to give Z. Nitrate of X on heating also gives Y along with a reddish brown gas P

which dissolves in water to give a diliute solution of a strong oxidising agent Q. Identify X, Y, Z, P & Q.​

Answer 1

Answer:

A metal X, used for galvanisation is zinc, which reacts with oxygen to give a white coloured amphoteric oxide , zinc oxide, which further reacts with sodium hydroxide to give sodium zincate (Na2ZnO2). Nitrate of Zinc on heating also gives Zinc oxide (ZnO) along with a reddish brown gas Nitrogen di oxide (NO2) which dissolves in water to give a dillute solution of a strong oxidising agent Nitric acid (HNO3)....

Hence, X is zinc(Zn)

Y is Zinc oxide (ZnO)

Z is sodium zincate(Na2ZnO2)

P is nitrogen dioxide(NO2)

Q is Nitric acid(HNO3)
