We are being asked to determine the equilibrium concentration of C2O42- in a solution of 0.20 M oxalic acid.
We will need the equilibrium constant for oxalic acid and construct an ICE chart to determine the equilibrium concentrations of the C2O42-.
Oxalic acid → H2C2O4
• can donate two protons (H+) → diprotic acid
• two equilibrium equations → two equilibrium constants
• Equilibrium constants (Ka) can be found in books or on the internet
Calculate the equilibrium concentration of C2O42− in a 0.20 M solution of oxalic acid.
Express your answer to two significant figures and include the appropriate units.
