Calculate the concentration of the hydronium ion([H3Ol+]) for a solution with the pH = 4.5
pH = -log(H3O^+)
To calculate the concentration of the hydronium ion ([H3O+]) for a solution with a given pH, we need to use the equation:
pH = -log[H3O+]
To find the concentration of the hydronium ion, we need to rearrange the equation:
[H3O+] = 10^(-pH)
Now, let's substitute the given pH value into the equation to calculate the concentration of the hydronium ion:
[H3O+] = 10^(-4.5)
Using a calculator, evaluating 10^(-4.5) gives us a concentration of approximately 3.16 x 10^(-5) M.
Therefore, the concentration of the hydronium ion in the solution with a pH of 4.5 is approximately 3.16 x 10^(-5) M.
