Consider an electrochemical cell constructed from the follow

Consider an electrochemical cell constructed from the following half cells, linked by a KCl salt bridge.

· an Al(s) electrode in 0.5 M Al₂(SO₄)₃solution
· a Pb(s) electrode in 1.0 M Pb(NO₃)₂ solution

Which electrode is the anode?

<?xml:namespace prefix = o ns = \"urn:schemas-microsoft-com:office:office\" />

A. Al

B. Pb

C. neither

WHY?

Solution

Al half cell will be the anode.
Since, Al has more tendency to get oxidised than Pb ( from electrochemical series ).
I hope this will help.
