Solution Summary

It finds the concentration of Ca2+ after the reaction. An aqueous solution is examined.

Solution Preview

In these questions, you treat them like a limiting reagent question, since it is quite obvious that CaC2O4 will precipitate (in the question, but also it has such a small Ksp).

If we precipitate all ...
