What is the hydronium ion concentration of an acid rain sample that has a pH of 3.45?
3.55 x 10^-4 M
pH = -log(H^+)
Substitute 3.45 for pH and solve.
Thank you
To determine the hydronium ion concentration of an acid rain sample with a pH of 3.45, we can use the equation:
pH = -log[H3O+]
First, rearrange the equation to solve for [H3O+]:
[H3O+] = 10^(-pH)
Substitute the given pH value (3.45) into the equation:
[H3O+] = 10^(-3.45)
Using a scientific calculator, evaluate 10^(-3.45):
[H3O+] ≈ 3.48 x 10^(-4) M
Therefore, the hydronium ion concentration of the acid rain sample is approximately 3.48 x 10^(-4) M.
