Question
When excess oxalic acid is added to CaCl2 solution, CaC2O4 is precipitated and the solution still contains some unprecipitated Ca2+. The reason is
Options
A.CaC2O4 is a soluble salt.
B.oxalic acid does not ionize at all.
C.the solution becomes acidic and hence, ionization of H2C2O4 is suppressed.
D.the solution becomes basic and hence, ionization of H2C2O4 increases.
