Question

The number of peroxide linkages in cro5 and h2so5 respectively are

Answer 1

Oxidation state of sulphur comes to be +8 but the maximum oxidation state of sulphur is +6 so by the formula, Caro's acid has only one peroxide linkage. Calculated oxidation state of chromium is +10 but the maximum oxidation state of chromium is +6 so it has 2 peroxide linkages

Answer 2

your answer

oxidation state of chromium is +10 but the maximum is +6 so it has 2 peroxide linkage while in sulphur it is +8 and maximum is +6 so 1 peroxide linkage

hope helps
