question 107

Multiple Choice

Consider a Galvanic cell constructed from the following half cells, linked by an external circuit and by a KCl salt bridge.- an Al(s) electrode in 1.0 M Al(NO₃) ₃ solution - a Pb(s) electrode in 1.0 M Pb(NO₃) ₂ solution
The balanced overall (net) cell reaction is

• A)Pb(s) + Al³⁺(aq) \(\rarr\) Pb²⁺(aq) + Al(s.)
• B)3Pb(s) + 2Al³⁺(aq) \(\rarr\) 3Pb²⁺(aq) + 2Al(s).
• C)3Pb²⁺(aq) + 2Al(s) \(\rarr\) 3Pb(s) + 2Al³⁺(aq).
• D)Pb²⁺(aq) + Al(s) \(\rarr\) Pb(s) + Al³⁺(aq).
