As the pka of an acid increase the acid will be

Answer 1

Answer:

As the pKa of an acid increases, the acidity nature of the solution decreases, hence it becomes weaker So option A is correct!

Answer 2

Answer:

As the pKa of an acid increases the acid will become weaker.

Explanation:

pKa values and the strength of the acid are inversely proportional to each other. A strong acid is an acid that breaks down completely in water into ions and attaches to the molecules of water.

pKa value of an acid shows how strong that particular acid is. If an acid has a low pKa, then it is a strong acid. Inversely if an acid has a high pKa value, then it is a weak acid. For example, Lactic acid is a strong acid as it has a pKa value of 3.8.

Thus, when the pKa increases, the strength of the acid decreases, i.e., the acid gradually becomes weaker.
