Question

Calculate the pH of a solution that has [H30*] = 5.2 x 10-7M

Answer 1

Answer:

pH ≈ 6.3

Explanation:

To calculate the pH of an aqueous solution, you need to know the hydronium ion (H₃O+) concentration in moles per liter (molarity).  The pH is then calculated using the expression:

      pH = - log [H₃O+]

Since the solution has an H₃O+ ion concentration of 5.2 × 10⁻⁷ M, we can plug that in and solve:

      pH = - log [5.2 × 10⁻⁷]

      pH = 6.28
