Does a weak acid partly dissociate in a solution?

Answer 1

Yes, we generally consider any acid that is weaker than the hydronium ion, H3O+ (the strongest acid that can exist in water) it does not dissociate fully.

For example: If we put HF, a weak acid, in water, it will exist in equilibrium with the hydronium ion.

HF + H2O <<---> F- + H3O+

With equilibria like this, we have two acids that are trying to protonate each other's respective conjugate base- the stronger acid will win. Because the hydronium ion is a stronger acid than hydrofluoric acid, it will more easily protonate fluoride than HF protonates water. Therefore we have a good amount of undissociated HF (our weak acid).

Answer 2

Yes, a weak acid will partly dissociate in a solution, meaning that some of the acid molecules will break apart into ions while others remain intact. This results in the formation of both hydronium ions and undissociated acid molecules in solution.

Answer 3

Weak acids will dissociate only partially in water.

Example: acetic acid or oxalic acid

Answer 4

Weak acid like acetic acid partially ionizes in water as their structure is complex

Answer 5

HC2H3O2 (acetic acid)

Answer 6

strong acids do.

Answer 7

weak

Answer 8

Yes
