Question

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

Answer 1

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 ]`

Step-by-step 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
