Question

ph when there are 1.6x10-7 moles of H+ in 500mL of solution

Answer 1

To calculate the pH of the solution with 1.6x10-7 moles of H+ in 500mL of solution, we first need to find the concentration of H+ ions in the solution.

First, calculate the concentration of H+ ions in the solution:
1.6x10-7 moles / 0.5 L = 3.2x10-7 mol/L of H+ ions

Next, calculate the pH using the formula:
pH = -log[H+]

pH = -log(3.2x10-7)
pH ≈ 6.5

So, the pH of the solution with 1.6x10-7 moles of H+ in 500mL of solution is approximately 6.5.
