Dear Ashish
I am trying to give goosd explanation.
Na2S2O3
Oxidation state of 'S' you do not know, ok
Oxidation state for sodium = 1, So, Two sodium gets (1+1)= 2
Your question is oxidation state for sulphur, So unknown, There are two sulphur atoms are there, we will write as 2x
Oxidation state for oxygen = -2.There are there are three oxygen atoms, So
(-2*3)= -6
Just apply in the avove molecular fomula,
Na2S2O3
(2+2x-6) = 0
(2-6)+2x= 0
-4+2x= 0
x " means sulphur atom = 2, So
Osidation state of sulphur is "2"
