Question

What is NOT true about the given chemical reaction,

HF(aq) + H2O(l)  F-(aq) + H3O+(aq)

BlackTom AI · Accepted Answer

Question restatement: The prompt asks which statement is NOT true about the reaction HF(aq) + H2O(l) → F-(aq) + H3O+(aq).

Option under consideration: 'H2O is an acid and F- is its conjugate base.'

Analysis of the reaction context: In this acid–base process, HF donates a proton (acts as the acid) to water. Water (H2O) accepts the proton and is reduced to its conjugate acid, H3O+. The species formed on the fluoride side, F-, is the conjugate base of the acid HF, not the conjugate base of water.

Why this option is not true:
- The statement claims water (H2O) behaves as an acid in this reaction, but the actual role is that water acts as a base (it accepts a proton from HF).
- It also claims F- is the conjugate base of water. In reality, F- is the conjugate base of HF. Water’s conjugate acid is H3O+.
- Therefore, labeling H2O as an acid and F- as its conjugate base misidentifies both the acid–base relationships: the true acid is HF, and the true conjugate base of HF is F-, while the conjugate acid of water is H3O+.

Implications for understanding: This helps distinguish which species donates a proton (HF) and which species accepts a proton (H2O), as well as correctly identifying conjugate pairs (HF/F-, H2O/H3O+).

In summary, the statement is not true because water does not act as the acid here, and F- is not the conjugate base of water; it is the conjugate base of HF.
