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.
