The answer to whether the given compounds are manganese(ii) or manganese(iii) are respectively; manganese(iii), manganese(ii),manganese(ii), manganese(iii), manganese(ii), manganese(iii)
The compounds are;
For us to determine the state of the manganese ions, we will look at the anions linked to it.
MnN; Here, on manganese the charge is +3 so it is manganese(iii).
MnO; Here, manganese has a charge of +2 and so it is manganese(ii)
MnBr₂; Here, Br has a charge of +2 and so it is manganese(ii)
Mn₂S₃; Here S has a charge of +3 so is manganese(iii).
Mn₃P₂; Here, Manganese has a charge of +2 and so is manganese(ii)
MnI₃; here manganese has a charge of +3 and so is manganese(iii).
