Part A
Calculate the cell potential for the following reaction that takes place in an electrochemical cell at 25°C.
Sn(s) | Sn2+(aq, 0.022 M) || Ag+(aq, 2.7 M) | Ag(s)
Sn2+(aq)+2eââSn(s) Eo=â0.14V
Ag+(aq)+1e1âAg(s) Eo=0.80V
1.01 V -0.83 V -0.66 V 0.01 V 1.31 V
Part B
How many electrons are transferred in the following reaction? (The reaction is unbalanced.)
Mg(s) + Al3+(aq) â Al(s) + Mg2+(aq)
