Calculate the oxidation number of 's' in `H_2SO_4` ?

Text Solution

Verified by Experts


O.N of oxygen in pero0XIde link is -1 each while the other oxygen atom have o0XIdation number of -2
`therefore` O.N of S = (+1) + (-2) + x + (2x - 1) + (2x -2) + 1 = 0 and x = +6
(By normal calculation ON of sulphur is +8 which is not possible fallacy)
