The standard reduction potential for Cu²+,
the voltage measured between a standard
hydrogen electrode and a Cu electrode
immersed in a solution where [Cu²+] = 1.00
M, is 0.340 V. The positive voltage indicates
that the following reaction is spontaneous.
H₂(g) + Cu²+(aq) → 2H*(aq) + Cu(s) What
would be the Cu²+ reduction potential if the
standard hydrogen electrode was kept the
same, but copper electrode were instead
immersed in a solution of 0.850 M NaOH
that was saturated with Cu(OH)₂? (The Ksp
of Cu(OH)2 is 2.20 × 10-²⁰.)
