Question

one molecule of an "ic" acid of a non metal having 5 electrons in valence shell reacts with a molecule of base to from a salt "X". The base corresponds to the metal with one electron in valence shell. If the salt so formed can react with the same base in 1:2 ratio predict the formula of the salt "X".​

Answer 1

Answer:

As the acid is having nonmetal with a valency 5, the acid is Phosphoric acid.

It reacts with a base which has metal with valency 1, let us assume the metal to be K, and the base as KOH

The reaction of acid with base to give salt is:

KoH + H_3 PO_4→ KH_2 PO_4 + H_2O

the reaction after balancing has the salt and base in the ratio 1 :2

KH_2 PO_4 + 2KOH → K_3 PO_4 + 2H_2O
