Answer 2

The valency or valence of a compound represents the combining capacity of an element, indicating the number of chemical bonds it can form. In the compound Al2(SO3)3, aluminum (Al) and sulfate (SO3) are the elements involved.

To determine the valency of Al in Al2(SO3)3, we need to consider the charges of the other elements. The sulfate ion (SO3) has a charge of 2-.

The formula Al2(SO3)3 suggests that there are two aluminum ions (Al3+) and three sulfate ions (SO3)2- in the compound.

To balance the charges, we need to have a total positive charge equal to the total negative charge. Since each aluminum ion carries a +3 charge and there are two of them, the total positive charge is 2*(+3) = +6. Each sulfate ion carries a -2 charge, and since there are three of them, the total negative charge is 3*(-2) = -6.

The compound Al2(SO3)3 has a net charge of 0 because the positive and negative charges balance out. Therefore, the valency of aluminum (Al) in Al2(SO3)3 is +3.
