Oxalic acid $\left(\mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4}\right)$ is a diprotic acid. By using data in Appendix $\mathrm{D}$ as needed, determine whether each of the following statements is true: (a) $\mathrm{H}_{2} \mathrm{C}_{2} \mathrm{O}_{4}$ can serve as both a Bronsted-Lowry acid and a Brønsted-Lowry base. (b) $\mathrm{C}_{2} \mathrm{O}_{4}^{2-}$ is the conjugate base of $\mathrm{HC}_{2} \mathrm{O}_{4}^{-}$. (c) An aqueous solution of the strong electrolyte $\mathrm{KHC}_{2} \mathrm{O}_{4}$ will have $\mathrm{pH}<7$.

Key Concepts

Brønsted-Lowry Acid-Base Theory

This theory defines acids as species that donate protons and bases as species that accept protons during a chemical reaction. It is a fundamental concept in acid–base chemistry, enabling the analysis of how various substances interact by exchanging protons rather than merely dissociating into ions.

Conjugate Acid-Base Pairs

Conjugate acid-base pairs consist of two species that interconvert by the gain or loss of a proton. When an acid donates a proton, it forms its conjugate base, and when a base accepts a proton, it forms its conjugate acid. This relationship is essential for understanding chemical equilibrium in acid–base reactions.

Diprotic Acids

Diprotic acids are acids capable of donating two protons in successive reactions, each with its own dissociation constant. The stepwise nature of their deprotonation significantly affects their behavior in solution, influencing factors such as the degree of ionization and the resulting pH.

Salt Hydrolysis and pH Determination

Salt hydrolysis involves the reaction of the ions from a dissolved salt with water, which can lead to an increase or decrease in the pH of the solution depending on the strengths of the parent acid and base. This concept is critical when predicting whether a solution will be acidic, basic, or neutral after a salt dissolves.
