Question

A voltaic cell is constructed with all the reactants and products in their standard states. Will
this condition hold as the cell operates? Explain.
What is the solubility of calcium fluoride in a buffer solution containing 0.45 M formic
acid and 0.20 M sodium formate?
Given: Ka for formic acid = 1.7 x 10-4
Ka for hydrofluoric acid = 6.8 x 10-4
Ksp for calcium fluoride = 3.4 x 10-11
No, the solutions will not remain at 1 M. At the anode the metal ion will increase and it will decrease at the cathode (assuming of course that it is a M/M^+||M^+/M cell.
I worked this problem for Tina below.
