Question

pH=pKa in which condition

Answer 1

Explanation:

The "operational" relationship between pKa and pH is mathematically represented by Henderson-Hasselbach equation:

pH = pKa + log [A-] / [HA]

where [A-] represents the deprotonated form and [HA] represents the protonated form.

One oft-cited solution to this equation is obtained by arbitrarily setting pH = pKa

pH is equal to the pKa of the acid, there are equal amounts of protonated and deprotonated acid molecules.
