Answer 1

Question 6

pka is inversely proportional to pH . If lower value is pka then stronger the acid and more ability to donate proton and higher the pH.

Here , pKa value lower for HA as compared to all so, pH will have the highest.

Therefore, HA will have the highest pH.

The correct option is KA.
