Chapter 20: Q38P (page 678)

Calculate the pKa's for the following acids:

(a) Lactic acid, Ka = 8.4 脳 10-4

(b) Acrylic acid, Ka = 5.6 脳 10-6

Short Answer

Expert verified

Thevalue of pKa for lactic and acrylic acid were calculated.

Step by step solution

01

Calculation the value of pKa for lactic acid

The formula can be denoted as,

pKa=-logKapKa=-log(8.4脳10-4)pKa=3.08

The pKa of lactic acid is 3.08.

02

Calculation the value of pKa for acrylic acid

The formula can be denoted as,

pKa=-logKapKa=-log(5.6脳10-6)pKa=5.25

The pKa of lactic acid is 5.25.
