A 1 liter solution contains 0.227 M acetic acid and 0.302 M potassium acetate. Addition of 0.113 moles of sodium hydroxide will: (Assume that the volume does not change upon the addition of sodium hydroxide.)

(e) No Change on pH

Explanation:

The question is not complete. The completed question is;

A 1 liter solution contains 0.227 M acetic acid and 0.302 M potassium acetate. Addition of 0.113 moles of sodium hydroxide will:

(a) Raise the pH

(b) lower the pH

(c) Raise the pH by several unit

(d) lower the pH by several unit

(e) No Change on pH

The mixture of 0.227 M acetic acid and 0.302 M potassium acetate, gives a buffer solution.

The mixture resists change in pH when the Sodiumhydroxide is added
