Divalent Anions (Anions Having a Valency of 2-)
Divalent anions means anions having a valency of 2- In other words,divalent anions means negative ions having a valency of 2- (two minus).Some of the important divalent anions or divalent negative ions are given below :
1.Oxide ion, 4.Sulphate ion,
2.Sulphide ion,5.Carbonate ion,
3.Sulphite ion,
