Question

What is the pH of a solution of HCl with a 0.051 M concentration of hydronium ions?

Answer 1

Answer:

The pH value of the solution comes out to be 1.29. The pH value is obtained by using the following expression shown below

$\textrm{pH} = -\textrm{log}\left [ H_{3}O^{+} \right ]$

Explanation:

Given concentration of hydronium ion = $\left [ H_{3}O \right ]^{+}$ = 0.051 M

The formula for finding the pH value is shown below

$\textrm{pH} = -\textrm{log}\left [ H_{3}O^{+} \right ] \\\textrm{pH} = -\textrm{log}\left ( 0.051 \textrm{ M} \right ) \\\textrm{pH} = 1.29$

Hence, the pH value of solution of HCl is 1.29
