Use the standard half-cell potentials listed below to determine which the following metals will dissolve in hydrochloric acid.
Cl2(g) + 2e + 2C1-(aq);
E° = 1.36 V 2H+(aq) + 2e + H2(g); E° = 0.00 V
a. Cu; E°(Cu2+/Cu) = +0.34V
b. Au; E°(Au3+/Au) = +1.50V
c. Al; E°(A13+/Al) = -1.66V
d. Ag; E°(Ag+/Ag) = +0.80V
e. Pt; E°(Pt2+/Pt) = +1.19V
