1. For each of the following reactions, balance the chemical
equation, calculate the emf, and calculate G° at 298 K. (Use the
smallest possible coefficients for H2O(l), H+(aq), and HO-(aq).
These may be zero.)
(a) Aqueous iodide ion is oxidized to I2(s) by
Hg22+(aq)
___ I-(aq) + ____Hg22+(aq) + ____H+ =
___I2(s) ____Hg(l) +____ H2O(l)
emf
_____V
G°
_____kJ
(b) In basic solution Cr(OH)3(s) is oxidized to CrO42-(aq) by
ClO-(aq).
____Cr(OH)3(s) + ____ClO-(aq) + _____OH-(aq)
= ______ CrO42-(aq) _____Cl-(aq) +
______H2O(l)
emf
_____V

_____kJ
(c) In acidic solution copper(I) ion is oxidized to copper(II)
ion by nitrate ion.
____Cu+(aq) + ____NO3-(aq) + ____H+(aq) =
_____Cu2+(aq) _____NO(g) + _____H2O(l)
emf
_____V
