Question

The formula of a phosphate of a metal $M$ , is $MP{O}_4$ . The formula of its nitrate will be

• A. $MN{O}_3$
• B. $M{(N{O}_3)}_2$
• C. $M{(N{O}_3)}_3$
• D. $M_2{(N{O}_3)}_2$

Answer 1

Answer: (C)

Formula of metal phosphate is $MP{O}_4$ . So, oxidation state of $M$ is $+III$ . $\therefore$ Formula of metal nitrate is $M{(N{O}_3)}_3$ .
