Answer:
pH ≈ 6.3
Step-by-step 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
