Calculate the oxidation number of the underlined element in the following molecules. Na_(2)ul(S_(2))O_(3) |
|
Answer» Solution :`Na_(2)S_(2)O_(3)` : Suppose, the oxidation NUMBER of each S atom in `Na_(2)S_(2)O_(3)` is x. Since `Na_(2)S_(2)O_(3)` is a NEUTRAL MOLECULE, we have `(+1)xx2+(x)xx2+(-2)xx3=0` or x=+2 HENCE, the oxidation number of each S atom in `Na_(2)S_(2)O_(3)` is +2. |
