In redox reaction we often deal with acids like H2S2O8,H2S2O7,H2SO5. My problem is that how to find out the oxidation state of sulphur in each of these. Its too difficult to remember the oxidation state of elements in such compunds because there are too many like these. So please tell me a method to deal with this problem.

Question

PASUPULETI GURU MAHESH · Answer

oxidation state of the sulphur =7 next one 6, next one 8 H2S2O8,H2S2O7,H2SO5 the oxidation state of the sulphur in each cpmpound in first one the explanation of answers is first you know the oxidation state of each element that is H=1, O=-2, =0 then solve it nowH2S2O8= 2(1)+2(x)+8(-2) then x= 7 where x is the oxidation state of sulphar in that compound like that you solve it. thank you
