MCQ
Addition of $\text{HCl}$ will not suppress the ionization of :
- AAcetic acid
- BBenzoic acid
- C$\ce{H_2S}$
- ✓Sulphuric acid
✓
Answer
Correct option: D.
Sulphuric acid
Any acid weaker than $\text{HCl}$ will be suppressed by $\text{HCl}$. Hence, among the given options, only sulphuric acid is an acid with comparable acidity strength to $\text{HCl}$. The same can also be verified using $\text{Ka}$ values from the data.
