Calculate the oxidation number of each sulphur atom in the following compounds.
(a) `Na_(2)S_(2)O_(3)``" "`(b)`Na_(2)S_(4)O_(6)``" "`( c)`Na_(2)SO_(3)``" "`(d)`Na_(2)SO_(4)`

Options

A. `Na_(2)S_(2)O_(3)`
B. `Na_(2)S_(4)O_(6)`
C. `Na_(2)SO_(3)`
D. `Na_(2)SO_(4)`

Explanation

(a) -2 an d+6 r
(b) +5 ,0,0 +5
(c ) Let the O.N of S in `Na_(2)SO_(3)` be x `therefore` 2(+1) +x+3 (-2)=0 or x=+4
(d) Let the O.N of S in `Na_(2)SO_(4)` be x `therefore` 2(+1)+x+4(-2)=0 or x=+6
