Question

The phosphate of a metal has the formula $MHP{O}_4$, the formula of its chloride would be:

• A. $MCl$
• B. $MC{l}_2$
• C. $MC{l}_3$
• D. $M_{2}C{l}_3$

Answer 1

Answer: (B)

$MC{l}_2$

$MHP{O}_4⟶M^{2+}+{P{O}_4}^{2-}$

The valency of $HP{O}_4$ has a valency of $-2$.

Therefore, the valency of metal has a valency of $+2$.

$M^{2+}+2C{l}^{-}⟶MC{l}_2$

Option B is correct .
