Vedclass · Answer

(C) The solubility product $(K_{sp})$ values for alkaline earth metal oxalates are very low. Specifically,the $K_{sp}$ values for $CaC_2O_4$,$SrC_2O_4$,and $BaC_2O_4$ are all quite small,meaning they are all sparingly soluble in water. When an oxalate solution (such as ammonium oxalate) is added to a mixture containing $Ba^{2+}$,$Sr^{2+}$,and $Ca^{2+}$ ions,all three ions will form insoluble white precipitates of their respective oxalates. Therefore,all three ions precipitate.

Which ion$(s)$ precipitate when an oxalate solution is added to a mixture of $Ba^{2+}$,$Sr^{2+}$,and $Ca^{2+}$?
