Vedclass · Answer

(B) Caro's acid is peroxymonosulfuric acid,with the chemical formula $H_2SO_5$.In $H_2SO_5$,there is one peroxy linkage $(-O-O-)$ where the oxidation state of each oxygen atom is $-1$.The other three oxygen atoms have an oxidation state of $-2$.Let the oxidation number of $S$ be $x$.Applying the sum of oxidation states: $2(+1) + x + 3(-2) + 2(-1) = 0$.$2 + x - 6 - 2 = 0$.$x - 6 = 0$.$x = +6$.

The oxidation number of $S$ in Caro's acid is ..........
