ph when there are 1.6 × 10^-7 moles of H+ in 500 ml of solution
To calculate the pH of a solution given the concentration of H+ ions, we can use the formula:
pH = -log[H+]
Given that there are 1.6 × 10^-7 moles of H+ ions in 500 ml of solution, we first need to determine the concentration of H+ ions in moles per liter (M):
1.6 × 10^-7 moles / 0.5 L = 3.2 × 10^-7 M
Now we can calculate the pH:
pH = -log(3.2 × 10^-7)
pH ≈ -(-6.495) ≈ 6.5
Therefore, the pH of the solution with 1.6 × 10^-7 moles of H+ ions in 500 ml is approximately 6.5.
