Question

What can we expect if we titrate a mixture of NH4+ and NH3 (a buffer) by a strong base NaOH?

Answer 1

What can we expect if we titrate a mixture of $\mathrm{NH_4^+}$ and $\mathrm{NH_3}$ (a buffer) by a strong base NaOH?

**Solution:**

The strong base NaOH displaces ammonium cation from its salt in the form of ammonia $\mathrm{NH_3}$: $\mathrm{NH_4^+ + NaOH + NH_3(a\ buffer) = NH_3 + H_2O + Na^+ + NH_3(a\ buffer)}$

We’ll feel to sense characteristic pungent smell.
