Explain when solutions of lanthanum (III) bromide as well as potassium oxalate are mixed, a precipitate of lanthanum (III) oxalate forms.
1) Define what is the morality of the potassium oxalate solution if 94.0 mL are necessary to react with 24.5 mL of 0.240 M lanthanum (III) bromide?
2) Define what mass of lanthanum (III) oxalate would be produced under the conditions above?
