What is the pH of <br> 0.000519 M NaOH?
Softa [21]

The pH of the sodium hydroxide (NaOH) solution at the given concentration of 0.000519 M is determined as 10.72.

<h3>What is pH of solution?</h3>

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

Concentration of the basic solution, [OH⁻] = 0.000519

pOH = -log[OH⁻]

pOH = -log[0.000519]

pOH = 3.28

<h3>pH of the solution</h3>

pH + pOH = 14

pH = 14 - pOH

pH = 14 - 3.28

pH = 10.72

Thus, the pH of the sodium hydroxide (NaOH) solution at the given concentration of 0.000519 M is determined as 10.72.
