Question
Oxalic acid ionizes in two stages in aqueous solution:
H2C2O4(aq) + H2O(€ )2H;0* (aq) + HC2O4 (aq)
Kal = 5.9 × 10²
HC,O, (aq) + H,O(e)2H;0*(aq) + C20?¯(aq)
K22 = 6.4 × 10-5
Calculate the equilibrium concentrations of C¿O²¯,
HC,O, H,C,O4, and OH- in a 0.10 M solution of
sodium oxalate (Na,C¿O4).
