Question

SHORT ANSWER. (SEE EXTRA SHEET FOR ANSWER)69.a. Write the reaction for the ionization of the weak acid HA in water.b. Write the reaction for the ionization of the conjugate base of the weak acid HA in water.

Answer 1

Explanation and Answer:

a) The ionization reaction of HA in water is given below:

`H_2O\text{ + HA}\rightarrow H_3O^++A^-`

The reaction above occurs between a weak acid and water. A weak acid donates a proton to water. This in turn forms a bronsted base (A-) and hydronium.

b) The conjugate base of HA is A-

The ionization reaction of the conjugate base in water is given below:

`A^-\text{ + H}_2O\rightarrow HA+OH^-`

When a base reacts with water, water donates an H+ ion to the base and this in turn froms a weak acid.

Basically, when water reacts with a weak acid, a base is formed. And when water reacts with a base, a weak acid is formed.
