Question

In which of the following compounds, $S$ atom has +6 oxidation state?

• A. $H_{2}S{O}_5$
• B. $H_2{S}_2{O}_8$
• C. $N{a}_2{S}_4{O}_6$
• D. $H_{2}S{O}_4$

Answer 1

Answer: (A), (B), (D)

The correct options are
A $H_{2}S{O}_5$
B $H_2{S}_2{O}_8$
D $H_{2}S{O}_4$

S is in +6 oxidation state in (A) $H_{2}S{O}_5$ (B) $H_2{S}_2{O}_8$ and (D) $H_{2}S{O}_4$

However in (C) $N{a}_2{S}_4{O}_6$, the $S$ atom is in $0$ and $+5$ oxidation states.
