3.
Use the Nernst equation to calculate the cell potentials of
the following cells at 298 K.
(a) 2 Ag*(aq)(0.50 M) + Ni(s)→2 Ag(s) + Ni²*(aq)(0.20 M)
(b) Cu(s) + PtCl,²-(aq)(0.10 M) →
Cu²+(aq)(0.20 M)
+PtCl,? (aq)(0.10 M) + 2 CI (aq)(0.40 M)
(c) Pb(s) + SO,- (aq)(0.30 M) + 2 AgCl(s) –
PBSO4(s) + 2 Ag(s) + 2 CI¯(aq)(0.20 M)
