Write the competing equilibrium that will occur when a strong acid is added to the following equilibrium: Ca (aq) + C2O4 (aq) -> CaC2O4 (s)
CaC2O4 ==> Ca^2+ + C2O4^2-
and H^+ + C2O4^2- ==> HC2O4^-
and H^+ + HC2O4^- ==>H2C2O4
For this reason, CaC2O4 is more soluble in an acid solution than in pure H2O.
