A galvanic cell consists of a mercury (Hg) electrode immersed in 0.26 L of 0.105 M Hg2+ solution and a silver (Ag) electrode immersed in 0.74 L of 1.44 M Ag+ solution. The galvanic cell is allowed to discharge at 25 °C until equilibrium is reached. What is the concentration of Hg2+ at equilibrium?
Data:
E° (V)
Hg2+ + 2 e− →
Hg(l) 0.854
Ag+ + e− → Ag(s) 0.800
Round your answer to two significant figures.
