Given:
The balanced chemical reaction:
2 Al (s) + 6 H⁺ (aq) → 2 Al³⁺ (aq) + 3 H₂ (g)
To Find:
The total number of moles of electrons transferred from Al to H+ when 2 moles of aluminium reacts.
Calculation:
- The given reaction can be split up in two half reactions as follows:
2 Al (s) → 2 Al³⁺ (aq) + 6 e⁻
6 H⁺ (aq) + 6 e⁻ → 3 H₂ (g)
- From first half reaction, it is clear that 2 moles of Al gives out 6 moles of electrons to become Al³⁺.
- From second half reaction, it is clear that these 6 moles of electrons are accepted by H⁺ to become H₂ gas.
- So, the total number of moles of electrons transferred from Al to H⁺ is SIX (6).
