pH is defined as the negative log10 of the hydrogen ion activity, aH+, although general chemistry texts commonly express it in terms of the hydronium ion concentration. Thus, pH = −log10 [H3O+], where [H3O+] represents the concentration of H3O+ in units of moles per liter (M). Calculate the pH or [H3O+], as required, for the following solutions.

{H3O+}= 5.79 X 10^-4M

Answer:

The pH value is 3.23

Explanation:

Given that,

[tex][H_{3}O^{+}]=5.79\times10^{-4}\ M[/tex]

We know that,

pH is defined as the negative log10 of the hydrogen ion activity,

We need to calculate the pH

Using formula of pH

[tex]pH=-log_{10}[H_{3}O^{+}][/tex]

Put the value of [tex][H_{3}O^{+}][/tex]

[tex]pH=-log_{10}(5.79\times10^{-4})[/tex]

[tex]pH=3.23[/tex]

Hence, The pH value is 3.23
