What is the [H3O+] of a solution if its pH = 8.26?

[H3O]=10^-8.26

[H3O]=5.49*10^-9

To determine the [H3O+] (concentration of hydronium ions) of a solution based on its pH value, you can use the equation:

pH = -log[H3O+]

First, rearrange the equation to isolate [H3O+]:

[H3O+] = 10^(-pH)

Now, substitute the given pH value into the equation:

[H3O+] = 10^(-8.26)

To calculate this value, you'll need to use a calculator or a scientific calculator app.

So, by evaluating the expression 10^(-8.26), you'll find that the [H3O+] of the solution is approximately 5.01 x 10^(-9) M (moles per liter) or 5.01 nanomoles per liter (nM).
