Question

hydrogen phosphate of certain metal has a formula MHPO4,the formula of metal chloride is
a)MCl
b) MCl3
c) MCl2

Answer 1

MCl2
HPO4 has a valency of - 2, so the metal has a valency of +2.

Answer 2

Answer: Option (C) is the correct answer.

Explanation:

Valency of $HPO_{4}$ is -2. Therefore, the metal attached to $HPO_{4}$ will have a valency of +2.

Thus, when this metal combines with chlorine then the reaction will be as follows.

           $M^{2+} + 2Cl \rightarrow MCl_{2}$

Thus, we can conclude that the the formula of metal chloride is $MCl_{2}$.
