Question

Give an equation to represent aluminum ions formation.

a) Al -> Al³+ + 3e⁻
b) Al -> Al²+ + 2e⁻
c) Al³+ -> Al + 3e⁻
d) Al²+ -> Al + 2e⁻

Answer 1

Aluminum ions are formed through the oxidation half-reaction where aluminum loses three electrons to form aluminum ions with a charge of 3+ (Option a).

Step-by-step explanation:

Aluminum ions are formed through the oxidation half-reaction where aluminum loses three electrons to form aluminum ions with a charge of 3+

The balanced equation for the formation of aluminum ions is:

Al -> Al³+ + 3e⁻ (Option a)
