Calculate the oxidation number of 's' in H_2SO_4 ?

Answer»

Solution :
O.N of oxygen in pero0XIde link is -1 each while the otheroxygen 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)
