Homework Help: chemistry

Posted by Tom on Tuesday, May 27, 2008 at 8:23pm.

A chemist wishes to determine the concentration of CrO4-2 ions electrochemically. A cell is constructed consisting of saturated calomel electrode (SCE) and a silver wire coated with Ag2CrO4. The SCE is composed of mercury in contact with a saturated solution of calomel (Hg2Cl2). The electrolyte solution in the half-cell is saturated KCl. The E°cell of the SCE half-cell is +0.242 V with respect to the standard hydrogen electrode. The half-reaction for the reduction of Ag2CrO4 is shown below.

How would you draw a galvanic cell for this question? I am lost right now.

How should I do this problem.
