Be sure to answer all parts. calculate the ph of the following two buffer solutions: (a) 1.4 m ch3coona/1.6 m ch3cooh. (b) 0.1 m ch3coona/0.2 m ch3cooh.
which is the more effective buffer? a. 1.4 m ch3coona/1.6 m ch3cooh b. 0.1 m ch3coona/0.2 m ch3cooh

a) pH = 4.68 (more effective)

b) pH =4.44.

Explanation:

The pH of buffer solution is obtained by Henderson Hassalbalch's equation.

The equation is:

a) pKa of acetic acid = 4.74

[salt] = [CH₃COONa] = 1.4 M

[acid] = [CH₃COOH] = 1.6 M

This is more effective as there is very less difference in the concentration of salt and acid.

b) pKa of acetic acid = 4.74

[salt] = [CH₃COONa] = 0.1 M

[acid] = [CH₃COOH] = 0.2 M
