###### Problem Details

You are developing an analytical method to measure the following reaction:

CaCO3(s) + 2 e– ⇌ Ca(s) + CO32– (aq)      E°+ = ?

Given the following information, what is the expected standard potential (Eo+) for the above reaction?

CaCO3(s) + 2 e → Ca(s) + CO32– (aq)            Ksp = 6.0 × 109

Ca2+(aq) + 2 e → Ca(s)                                   E° = –2.868
