Question

Identify the salt(s) of an oxyacid formed from univalent metal ($M$).

• A. $M_{2}S{O}_4$
• B. $M(N{O}_3{)}_2$
• C. $M_{3}Cl{O}_3$
• D. $MHC{O}_3$

Answer 1

Answer: (A), (D)

The correct options are
A $M_{2}S{O}_4$
D $MHC{O}_3$

Since the metal is univalent, its sulphate and hydrogen carbonate have formulae $M_{2}S{O}_4$ and $MHC{O}_3$ respectively. The chlorate and nitrate have formula, $MCl{O}_3$ and $MN{O}_3$ respectively.
In the given options, $M_{2}S{O}_4$ and $MHC{O}_3$ are correct.
