Calculate the [H+] in a solution that has a pH of 9.00.
pH = -log(H^+)
Substitute and solve for (H^+). You should obtain 1E-9.
To calculate the [H+] (hydrogen ion concentration) in a solution given pH, we can use the equation:
[H+] = 10^(-pH)
Substituting pH = 9.00 into the equation, we get:
[H+] = 10^(-9.00)
Using a calculator, we find that:
[H+] ≈ 1.0 x 10^(-9) or 0.000000001
Therefore, the hydrogen ion concentration in the solution is approximately 1.0 x 10^(-9) moles per liter, or 0.000000001 moles per liter.
To calculate the concentration of hydrogen ions ([H+]) in a solution with a pH of 9.00, we can use the equation:
pH = -log[H+]
Rearranging the equation, we have:
[H+] = 10^(-pH)
Substituting the given pH value of 9.00 into the equation, we get:
[H+] = 10^(-9.00)
Now, we can use a scientific calculator or the exponent rule to solve the equation. Taking the negative exponent of 9.00, we have:
[H+] = 1.0 x 10^(-9.00)
Evaluating this exponential expression, we get:
[H+] = 1.0 x 10^(-9.00) = 1.0 x 10^(-9)
Therefore, the concentration of hydrogen ions ([H+]) in a solution with a pH of 9.00 is 1.0 x 10^(-9) (or 0.000000001).
