what is the pH

[H3O+] = 5.9×10−2 M

pH = -log(H3O^+)

Substitute and solve for H.

To determine the pH, which represents the acidity or alkalinity of a solution, you need to use the formula:

pH = -log[H3O+]

Given that the [H3O+] (hydronium ion concentration) is 5.9×10^−2 M, you can calculate the pH as follows:

pH = -log(5.9×10^−2)

Using a scientific calculator or log table, the calculation would be:

pH = -log(0.059) ≈ 1.23

Therefore, the pH of the solution is approximately 1.23.

To find the pH, you need to use the concentration of the hydronium ion ([H3O+]). The pH is a measure of the acidity or alkalinity of a solution. It is defined as the negative logarithm (base 10) of the hydronium ion concentration.

In this case, the concentration of the hydronium ion ([H3O+]) is given as 5.9×10−2 M.

To find the pH, you can use the formula:

pH = -log[H3O+]

Substituting the given value:

pH = -log(5.9×10−2)

Now, you need to take the negative logarithm of the hydronium ion concentration. This can be done using a scientific calculator or by using the logarithm function on a calculator:

pH ≈ -log(5.9×10−2) ≈ -(-1.23) ≈ 1.23

Therefore, the pH of the solution with a hydronium ion concentration of 5.9×10−2 M is approximately 1.23.
