question 61

Multiple Choice

Consider an electrochemical 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)\(\to\) Pb²⁺(aq)+ Al(s.)
• B)3Pb(s)+ 2Al³⁺(aq)\(\to\) 3Pb²⁺(aq)+ 2Al(s).
• C)3Pb²⁺(aq)+ 2Al(s)\(\to\) 3Pb(s)+ 2Al³⁺(aq).
• D)Pb²⁺(aq)+ Al(s)\(\to\) Pb(s)+ Al³⁺(aq).
