A solution of acetic acid that has a concentration of 0.10 moles per liter has a pH of 2.87. What is the likely pH of a 0.10 mole per liter solution of the conjugate base sodium acetate? A. 8.97
B. 1.00
C. 2.87
D. 4.74
E. 13.00

The correct option is A) 8.97

Explanation:

To calculate the of a reaction, we use the equation:

where,

= acid dissociation constant of acetic acid =

= base dissociation constant

Putting values in above equation, we get:

To calculate the hydroxide ion concentration of conjugate base, we use the equation:

where,

[Conjugate base] = 0.10 M

Putting values in above equation, we get:

To calculate the pOH of the solution, we use the equation:

To calculate the pH of the solution, we use the equation:

pH + pOH = 14

pH + 5.03 = 14

pH = (14 - 5.03) = 8.97

Hence, the correct option is A) 8.97
