Question
Assertion: The formula of aluminum sulphate is Al2(SO4)3Reason: The valency of aluminum ion is +3 and sulphate ion is -2
Solution
Assertion: The formula of aluminum sulphate is Al2(SO4)3. Reason: The valency of aluminum ion is +3 and sulphate ion is -2.
To determine the formula of aluminum sulphate, we need to consider the valency of the aluminum ion and the sulphate ion.
-
The valency of the aluminum ion is +3. This means that aluminum has a tendency to lose three electrons to achieve a stable electron configuration.
-
The valency of the sulphate ion is -2. This means that sulphate has a tendency to gain two electrons to achieve a stable electron configuration.
-
To balance the charges, we need two aluminum ions (each with a charge of +3) to combine with three sulphate ions (each with a charge of -2).
-
The formula for aluminum sulphate is therefore Al2(SO4)3, indicating that two aluminum ions combine with three sulphate ions.
In conclusion, the formula of aluminum sulphate is Al2(SO4)3, based on the valency of the aluminum and sulphate ions.
