Question

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

• A. $MCl$
• B. $MCl_2$
• C. $MCl_3$
• D. $M_2Cl_3$

Answer 1

Answer: (B)

$MCl_2$

Answer 2

Since the phosphate of a metal is $MHPO_{4}$ , therefore, metal M must be divalent, i.e., $M^{2+}$ . As a result, the formula of its chloride is $MCl_2.$
