Question

The salt of an oxyacid of a metal M contains one sulphur and four oxygen atoms

The oxyacid of the salt is

• A. $H_{2}S{O}_4$
• B. $H_{2}S{O}_3$
• C. $H_2{S}_2{O}_7$
• D. $H_{2}S$

Answer 1

The correct option is A $H_{2}S{O}_4$

The salt of an oxyacid of a metal M contains one sulphur and four oxygen atoms. The oxyacid of the salt is $H_{2}S{O}_4$. One sulphur and four oxygen atoms indicate sulphate ion $\left(S{O}_4^{2-}\right)$. Hence, the salt is metal sulphate and the oxyacid is sulphuric acid.
