Question 1 1 pts Finding pka given concentrations Look at sample problem 18.7. Write a balanced chemical equation and the corresponding Ka expression. Do an ICE chart. Since pH is given you have the Ht concentration. You are also given the original concentration of the acid. Complete the E of the ICE chart and input those values into the Ka expression. Phenylacetic acid (see below-monoprotic acid) builds up in the blood of persons with phenylketonuria, an inherited disorder that, if untreated, causes mental retardation and death. A study of the acid shows that the pH of 0.09 M phenylacetic acid is 2.07. What is the pKg? Remember pka = -log{Ky} Enter to 3 decimal places. .
