Answer
This mixture results in a buffer solution.
Work Step by Step
1. Try to identify conjugate acid-base pairs.
First solution: $NH_3$
Second solution: $N{H_4}^+$ and $Cl^-$
- The first solution has $NH_3$, and the second one has $N{H_4}^+$, so, since they are a conjugate pair, and they are in a simillar concentrations, the mixture will result in a buffer solution.
