Question Calculate the equilibrium concentrations of H₂O+, HC₂O, and C₂02 in a 0.10 M solution of the weak diprotic acid oxalic acid (H₂C₂O4). Note that the K₂ values for oxalic acid are as follows: Ka 5.9 x 10-2 and Ka = 6.4 x 10-5 Select the correct answer below: O [HC₂0] 1.2 x 10-2 M: [H₂O*] = 4.8 x 10-2 M: (C₂0,2-]- 8.9 × 10-5 M O [HC₂0,1-5.3 x 10-2 M: [H₂O*] - 5.3 x 10-2 M: [C₂02] = 6.4 × 105 M O [HC₂0] 6.4 x 105 M: [H₂O+] = 6.4 x 105 M: [C₂0,2] = 5.9 × 10-² M O [HC₂0]=7.4 x 10-3 M: [H₂O+] = 7.4 x 10- M: [C₂0,21] =2.0 × 10 M FEEDBACK SUBMIT
