What is the pH level of a solution with hydronium ion concentration of 0.0034?

The pH of a solution is calculated using the formula:

pH = -log[H3O+]

where [H3O+] is the concentration of hydronium ions in the solution.

Given that the hydronium ion concentration [H3O+] is 0.0034, we can substitute this value into the formula:

pH = -log(0.0034)

Now, we just need to calculate the value of -log(0.0034) using a calculator.

The result is approximately 2.47.

So, the pH of the solution is approximately 2.47.
