Explanation:

Data obtained from the question include:

[H3O+] = 0.0001 M

pH = ?

pH is the negative logarithm of the hydrogen ion or hydronium ion. It is written as:

pH = - Log [H3O+]

Now inputing the value of [H3O+] into the equation above, the pH value can be obtained as follow illustrated below

pH = - Log [H3O+]

[H3O+] = 0.0001 M

pH = - Log 0.0001

pH = 4

Therefore, the pH of the solution is 4.
