Chapter 20: Q39P (page 678)

Calculate the Ka's for the following acids:

(a) Citric acid, pKa = 3.14

(b) Tartaric acid, pKa = 2.98

Short Answer

Expert verified

Thevalue of Ka for citric and tartaric acid were calculated.

Step by step solution

01

Calculation the value of Ka for citric acid

The formula can be denoted as,

pKa=-logKaKa=10-pKaKa=10-3.14Ka=7.2脳10-4

The Ka of citric acid is with pKa is7.2脳10-4.

02

Calculation the value of Ka for tartaric acid

The formula can be denoted as,

pKa=-logKaKa=10-pKaKa=10-2.98Ka=1脳10-3

The Ka of tartaric acid is with pKa is1脳10-3.
