Question

required for
How many electrons are
dischanging
0.5 mol of Al3+ ions.​

Answer 1

Explanation:

Here, Charge on one mole of Al

3+

 is 3 moles. The discharge reaction is as follows:

Al

3+

+3e

−

⟶Al

According to the reaction for every mole aluminium ion, 3 electrons are required to discharge it. Hence for one mole of aluminium ion 3 moles of electrons are required.
