If a solution has a pH of 8.14, calculate [H3O+]?
pH is the logarithm of [H3O+], multiplied by (-1)
-log[H3O+] = 8.14
To calculate the concentration of H3O+ (also known as hydronium ion concentration) from the pH value, we can use the equation:
pH = -log[H3O+]
First, rearrange the equation to solve for [H3O+]:
[H3O+] = 10^(-pH)
Now, substitute the pH value of 8.14 into the equation:
[H3O+] = 10^(-8.14)
Using a calculator, the value of [H3O+] is approximately 5.62 x 10^(-9) M (moles per liter).
To calculate the concentration of H3O+ (hydronium ions) in a solution given the pH, you can use the equation:
pH = -log[H3O+]
First, rearrange the equation to isolate [H3O+]:
[H3O+] = 10^(-pH)
Now, substitute the given pH value of 8.14 into the equation:
[H3O+] = 10^(-8.14)
Using a scientific calculator or an online calculator, calculate 10^(-8.14):
[H3O+] ≈ 5.87 x 10^(-9) mol/L
Therefore, the concentration of H3O+ in the solution is approximately 5.87 x 10^(-9) mol/L.
