Question

In the following chemical reaction

HF + H2O  H3O+ + F-

BlackTom AI · Accepted Answer

In the given reaction, HF donates a proton to water: HF + H2O -> H3O+ + F-. This is a Bronsted-Lowry acid-base process. The species that donates the proton is HF, so HF is the acid, and F- is its conjugate base (the species formed after deprotonation of HF).

Water (H2O) accepts the proton to become H3O+. Since H2O accepts a proton, it acts as a base in this reaction, and its conjugate acid is H3O+ (the species formed after protonation of H2O).

Therefore, identifying the roles: HF is the acid, F- is its conjugate base; H2O is the base, and H3O+ is its conjugate acid.

This aligns with fundamental acid-base theory: conjugate pairs are related by the gain or loss of a single proton, and the direction of proton transfer determines which species act as acids and bases.

Note: no alternative answer options were provided in the prompt to critique or compare against this statement, but the reasoning above explains why H2O behaving as a base and H3O+ being its conjugate acid is consistent with the reaction.
