Answer : The pH of a solution is, 4.5
Explanation : Given,
Moles of benzoic acid = 0.15 mol
Moles of sodium benzoate = 0.30 mol
Volume of solution = 1.00 L
The dissociation constant for benzoic acid =
First we have to calculate the value of .
The expression used for the calculation of is,
Now put the value of in this expression, we get:
Now we have to calculate the pH of a solution.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Therefore, the pH of a solution is, 4.5
