Another radical = Nitride (N 3-) Valency of nitride (N 3-) = 3 (d) Aluminium sulphate — Al 2 (SO 4) 3. Here valency of aluminium is 3. Another radical = Sulphate (SO 4 2-) Valency of (SO 4 2-) = 2
The valency of a sulfate ion is -2, meaning it has a charge of -2 due to the presence of four oxygen atoms and a sulfur atom. This valency allows the sulfate ion to form compounds with metals and ...
Aluminimum sulphate is made up of aluminium ions (Al^(3+)) and sulphate ions (SO(4^(2-)) . The valency (or charge) of aluminium ions is 3+ whereas the valency or charge of sulphate ion is 2-. The formula for aluminium sulphate can be worked out as follows : Thus, the formula of aluminimum sulphate is Al(2)(SO(4))(3).

Sulphate ion. It is an ion of sulphur oxide carrying a double negative charge. (SO 4)-2 accepts 2 electrons from others. Total valency can be calculated by adding the valency of the sulphur and oxygen. S= +6, O= -2. Total valency= +6 + (4x-2) = +6-8 = -2; So the valency of sulphate ion is -2; The valency of sulphate ion is-2
