Question

In the equation HF + H2O H3O+ + F– (a) H2O is a base, and HF is its conjugate acid. (b) H2O is an acid, and HF is the conjugate base. (c) HF is an acid, and F– is its conjugate base. (d) HF is a base, and H3O+ is its conjugate acid. (e) HF is a base, and F– is its conjugate acid.

Answer 1

Answer:

Option c.

Explanation:

This is the equation:

HF  +  H₂O  ⇄   H₃O⁺  +  F⁻     Ka: 3.5×10⁻⁴

So the HF is the weak acid which donates the proton to water, so the water becomes a base cause accepted it.

The hydronium will release the proton, then. It is the conjugate acid, from water and the F⁻ which would accept a proton to form the HF, it is the conjugate strong base.

In conclussion, HF is an acid, and F– is its conjugate base

Answer 2

Answer:

its c
