Write the competing equilibrium that will occur when a strong acid is added to the following equilibrium: Ca (aq) + C2O4 (aq) -> CaC2O4 (s)

  • General Chemistry -

    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.
