The pH of a 0.0100 M sodium benzoate solution is determined as 8.09.
<h3>What is pH of a solution?</h3>
The pH of a solution is a measure of hydrogen (H+) ion concentration, which is, in turn, a measure of acidity of the solution.
pH is can also be determined from pOH of the solution as shown below;
pH = 14 - pOH
<h3>
pH of the benzoate solution</h3>
let the hydroxyl concentration, OH = x
x²/M = kb
x²/0.01 = 1.5 x 10⁻¹⁰
x² = 1.5 x 10⁻¹²
x = √(1.5 x 10⁻¹²)
x = 1.2247 x 10⁻⁶
pOH = - log(OH⁻)
pOH = -log( 1.2247 x 10⁻⁶)
pOH = 5.91
<h3>Calculate the value of the pH</h3>
pH = 14 - 5.91
pH = 8.09
Thus, the pH of a 0.0100 M sodium benzoate solution is determined as 8.09.
