Question
Consider a saturated solution of calcium oxalate, CaC204, in which the following equilibrium can
оccur:
CaC204(s) = Ca2* (aq) + C2042- (aq)
Ksp = 1.3 x 10-8
C20,2- (aq) + H20 (I) P HC204 (aq) + OH (aq)
НС204 (ag) + Н,0 () — н,с204 (ag) + он (аq)
If the pH is fixed at 2.30 (then charge balance becomes invalid), find the concentration of
Ca2+ in the solution. Assume y =1 for all species.
