Vedclass · Answer

(B) The given formula of the metal phosphate is $MHPO_4$. In this compound,the phosphate group is the hydrogen phosphate ion,which is $HPO_4^{2-}$. Since the overall charge of the compound must be zero,the metal ion $M$ must have a charge of $+2$ to balance the $-2$ charge of the $HPO_4^{2-}$ ion. Therefore,the valency of the metal $M$ is $2$. When this metal forms a chloride,the chloride ion is $Cl^-$. By criss-crossing the valencies,the formula of the metal chloride is $MCl_2$.

The phosphate of a metal has the formula $MHPO_4$. The formula of its chloride would be
