Als) → A13+ (aq) + 3 e-
Sn2+ (aq) + 2e- → Sn(s)
based on the half-reactions represented above, which of the following is the balanced ionic equation for the oxidation-reduction reaction between al(s) and sn2+(aq) ?

Answer :

The balanced ionic equation for the oxidation reduction reaction between Al(s) and Sn2+(aq) is 3 Al(s) + 2 Sn2+ (aq) → 3 Al3+(aq) + 2 Sn(s)  

what is redox reaction balancing?

To counteract this, we will separately write each oxidation and reduction reaction and explicitly mention the quantity of electrons in each. Half reactions are what are known as the oxidation and reduction processes separately.

Als) → A13+ (aq) + 3 e-

Sn2+ (aq) + 2e- → Sn(s)

3 Al(s) + 2 Sn2+ (aq) → 3 Al3+(aq) + 2 Sn(s)

The half reactions will then be combined into a full reaction, which should then be balanced, by doing multiples of each reaction until the quantity of electrons on each side totally cancels. The half reaction method is the name for this technique for redox reaction balancing.
