14.5 Exercise 1

Which of the following concentrations would be practically equal in a calculation of the equilibrium concentrations in a 0.134-M solution of H₂CO₃, a diprotic acid: $\left[\text{H}_{3} \text{O}^{+}\right] ,$ [OH⁻], [H₂CO₃], $\left[\text{HCO}_{3} ^{−}\right] ,$ $\left[\text{CO}_{3} ^{2−}\right] ?$ No calculations are needed to answer this question.
