A student constructs a galvanic cell that has a chromium, Cr, electrode in a compartment containing a 1.0 M chromium(II) nitrate, \(\ce{Cr(NO3)2}\) , solution and a silver, Ag, electrode in a compartment containing 1.0 M silver nitrate, \(\ce{AgNO3}\) , solution. A salt bridge containing a 1.0 M potassium chloride, KCl, solution connects the two compartments. When the student measures the cell potential, the value is far from the ideal predicted value. What is the cause of this discrepancy?
