(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

What is the maximum [Ca2+] that can exist with 5.2e-4 M c2O4 2- without precipitating? Ksp for CaC2O4 = 2.6e-9.

2. Relevant equations

Well, the Ksp and M is given, I don't know how to apply them.

3. The attempt at a solution

I need help because I missed the lesson.

Thank you.
