Want this question answered?
first of all its not chemical equation is chemical formula Potassium Sulphate: K2SO4 Potassium Sulphite: K2SO3
Formula: SO32- and SO42-
Coincidence! the oxidation number of sulfur in sufate is +6, in sulfite is +4. Sulfate is SO42-, sulfite is SO32- Personally I do not like using the word valency in this context, valency usually refers to elements- and is the number of bonds that an elemnt can form to other elemnts- it is an old term. In the context of ions charge seems to be a better word.
-2
No. Ammonium Sulphate may be present in some fertilisers, but not sulphite.
The sulfite ion has a valency of 2.
The formula for a sulphate ion is SO42- so the valency of a sulphate ion is -2.

The sulfate anion has a valency of 2-, i.e. it is SO4^2-
i think its 2
-2
magnesium has a valency of 2
