Above is a concentration cell for measuring Ksp for silver bromide. Given that the voltage for this cell at 298K is E=0.739 V, and that the overall reaction in this cell concentration cell is Use the data above to calculate pKsp, at equilibrium where pKsp = -log(Ksp) (note that when set-up with a voltmeter like this no significant current is drawn and the system reaches equilibrium) Ag cathode 50 mL of 1.0M AgNO, Agiaq) + Braq) = AgBr (s) + Ag anode 50 mL of 1.0M AgBr A+A) A+B-AgBr+ e COM VEMA 0.739 multimeter
