Question

One molecule of an "ic" acid of a non-metal having 5 electrons in valence shell reacts with a molecule
of base to form 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:

The chemical formula for the salt X is KH2PO4

Explanation:

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 + H3PO4  ====  KH2PO4  + H20

If the salt is made to react with the base, the reaction after balancing has the salt and base in the ratio 1 :2

as shown below :

KH2PO4 + 2KOH ==== K3PO4 + 2 H20

Hence the chemical formula for the salt X is KH2PO4
