Weak acid , determination of Ka
Hey there. I am having trouble with this question.
Phenylacetic acid (C6H5CH2COOH) is one of the substances that accumulates in the blood of people with phenylketonuria, and inherited disorder that can cause mental retardation or even death. A 0.085 M (mol/L) solution of C6H5CH2COOH has a pH of 2.68. Calculate the Ka value for this acid.
