A buffer contains significant amounts of ammonia and ammonium chloride. part a write an equation showing how this buffer neutralizes added acid (hi).

Hello!

When HI is added, the buffer reacts in the following way:

1) Neutralizing of the Acid:

HI + NH₄OH → NH₄I + H₂O

2) Dissociation of the salt of a weak acid:

NH₄I → NH₄⁺(aq) + I⁻ (aq)

3) Dissociation of a weak acid to form H₃O⁺ (very little):

NH₄⁺ + H₂O ⇄ NH₃ + H₃O⁺

This series of reactions show how the adding of a strong Acid can be neutralized by the buffer, releasing instead very little amounts of Hydronium ions.

The equation showing the buffer neutralizes acid is, when Hi is added, the reaction is:

[tex]\rm HI + NH_4OH = NH_4I + H_2O[/tex]

What is a buffer solution?

A buffer solution is made up of a weak acid and the conjugate base.

There are the processes following for neutralization of the buffer solution

a. Neutralization of the acid:

[tex]\rm HI + NH_4OH = NH_4I + H_2O[/tex]

b. Dissociation of salt of the weak acid:

[tex]\rm NH_4I = NH_4^+(aq) + I^- (aq)[/tex]

c. Dissociation of weak acid to form [tex]\rm H_3O^+[/tex]

[tex]\rm NH_4^+ + H_2O = NH_3 + H_3O^+[/tex]

Thus, these processes show that, on adding a strong acid, the buffer solution can be neutralized.
