Question

When some amount of sodium acetate is further added to a mixture of acetic acid and sodium acetate, then pH of the solution:

• A. Increases
• B. Decreases
• C. Remains same
• D. None of the above can be predicted from given information

Answer 1

The correct option is A Increases

For an acidic buffer:

$pH=p{K}_a+\log \frac{\left[Sodiumacetate\right]}{\left[AceticAcid\right]}$
When the concentration of sodium acetate is increased, the value of pH will increase.
