Question

A buffer contains significant amounts of ammonia and ammonium chloride.Enter an equation showing how this buffer neutralizes added aqueous acid (HCl). (See pictures of Part A and B below)

Please give steps and reasoning for the answer.

Part A Enter an equation showing how this buffer neutralizes added aqueous acid (HCI) Express your answer as a chemical equation. Identify all of the phases in your answer. HCl(aq) + NH, (aq NH, Cl(aq) Submit revious Answers Request Answer X Incorrect; Try Again; 5 attempts remaining Recall that HCl is a strong acid reacting with a weak base.

Explanation / Answer

2. if we only conside anion exchange then

NH4Cl + NaOH --> NH4OH + NaCl this reaction comes into mind. bit here NH4OH decomposes into NH3 and H2O so updated equation for buffer will be

NH4OH(aq) + NaOH(aq) --> NH3(g) + H2O(l) + NaCl(aq)

1. Here

NH3 + HCL ---> NH4+ + Cl-

The NH3 part of the buffer will react with HCl to form NH4+ which is the acid form of the buffer.

since NH3 is a much weaker base than OH^-1 and NH4+ is a much weaker acid than HCl this means there will be small change in values of ph which is the fundamental of buffer that is it resisits the change in pH.
