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}} $ .
