Problem: What pH buffer solution is needed to give a Mg2+ concentration of 3.0×10−2 M in equilibrium with solid magnesium oxalate?

FREE Expert Solution

We have to determine the pH of a buffer solution that can produce a Mg2+ ions concentration of 3.0×10-2 M.


We will solve this problem through these steps:

Step 1: Determine the concentration of oxalate ions using the Ksp of magnesium oxalate.

Step 2: Write an equation for the dissociation of oxalate ions in solution.

Step 3: Determine an overall equation combined with the dissociation of magnesium oxalate.

Step 4: Find the pOH and pH of solution.
