Question

HF is a week acid. What particles would you expect to find in a solution of HF(aq)?
HF, H+ and F- particles
HF particles only
H+ and F- particles
H+ particles only

Answer 1

Answer:

HF, H+ and F- particles

Explanation:

The particles expected to be in an aqueous solution of a weak acid, HF, would be HF, H+ and F- .

A weak acid is one that does not dissociate completely in aqueous solutions. Hence, the dissociated particles are in equilibrium with the solution of the acid itself.

Thus, for weak acid, HF:

 HF ⇌ H+ + F-
