You will find it useful to keep in mind that NH3​ is a weak base

Answer

The reaction taking place here is between hydrobromic acid (HBr) and ammonia (NH3). HBr donates a proton (H+) to NH3, resulting in the formation of ammonium ion (NH4+) and bromide ion (Br-).

Chemical Equation:

3. Neither acids nor bases: NH4Br (formed as a result of the reaction between HBr and NH3).

Step 2: Reaction 2 (0.13 mol of NaOH added to 1.0 L of a solution which is 1.1 M in both NH3 and NH4Cl):

3. NH4Cl ⟶ NH4+ + Cl-

After these reactions reach equilibrium, we can determine the major species present:

6. Neither acids nor bases:

NH4Cl (dissociates into NH4+ and Cl- ions, but this is not involved in proton transfer reactions in this case).

• Neither acids nor bases: NH4Br (resulting from the reaction).

For the reaction with 0.13 mol of NaOH in a 1.1 M NH3 and NH4Cl solution:
