COMEDK · Chemistry · 8. Ionic Equilibrium
Select the \(\mathrm{p} K_{a}\) value of the strongest acid from the following.
- A 2
- B 4.5
- C 1
- D 3
Answer & Solution
Correct Answer
(C) 1
Step-by-step Solution
Detailed explanation
The acidic strength of an acid increase with ionisation. The value of \(\mathrm{p} K_{a}\) is inversely proportional to ionisation constant \(\left(\bar{K}_{a}\right)\). \(\therefore\) The acid with \(\mathrm{p} K_{a}\) value \(1.0\) is strongest.
