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.

Have a nice day!

2NH4CL + Ba(OH)2 --> 2NH3 + 2H2O + BaCl2 (acid neutralizes base; the product has to have all the components it started with in the reactants; since you know that water and a base will be a product, group the two leftovers together)

- HA(aq) + OH^-(aq)rightarrow H_2O(l) + A^-(aq)

Explanations:- KOH is a strong base that gives hydroxides ion in the aqueous solution. When it's added to a buffer solution, this hydroxide ion is neutralized by the weak acid, HA present in the buffer and try to maintain it's pH.

Ba(OH)2 can be neutralized by adding an acid to the solution. We can add HCl to produce:

Ba(OH)2 + 2HCl ===> BaCl2 + 2H2O ; producing a salt BaCl2 and water. 

or we can add H2SO4 to produce:

Ba(OH)2 + H2SO4 ===> BaSO4 + 2H2O; producing a salt, BaSO4, and water. 

Here, the buffer is NH₄Cl + NH₃
The strong base is added to the buffer solution, then the salt reacts with base to form weak base and water, which does not alter the pH

NH₄Cl + CsOH → NH₃ + CsCl + H₂O
NH₄⁺ + OH⁻ → NH₃ + H₂O

When we add a strong acid to the buffer solution, the base NH₃ reacts with acid and forms salt, which does not alter the pH
NH₃ + H⁺ → NH₄⁺

I have no idea!i don’t know what it is,I’m sorry.
If a strong acid is added to a buffer, the conjugate base of buffer will reacts with the H⁺ from the strong acid to form the weak acid. The H⁺ gets absorbed by the CH₃COO⁻ instead of reacting with water to form H₃O⁺ so the pH will remain constant, The equation is:
CH₃COO⁻ + HNO₃ → CH₃COOH + NO₃⁻

Buffer converts strong acid to weak acid
