Ph of [OH-] = 0.024

To calculate the pH from the hydroxide ion concentration [OH-], we can use the formula:

pH = 14 - pOH

Given that [OH-] = 0.024 M, the pOH can be calculated as follows:

pOH = -log[OH-] = -log(0.024) = 1.62

Now, we can calculate the pH:

pH = 14 - pOH = 14 - 1.62 = 12.38

Therefore, the pH of a solution with [OH-] = 0.024 M is approximately 12.38.
