Final answer:
To calculate the [OH-] in a solution with a pH of 12.52, use the formula pH + pOH = 14.00. Subtract the pH from 14 to get pOH, then calculate [OH-] using the concentration of hydroxide ions formula.
Step-by-step explanation:
To calculate the [OH-] in a solution with a pH of 12.52, we can use the formula pH + pOH = 14.00. Since the pH is 12.52, we can calculate the pOH by subtracting the pH from 14.00:
pOH = 14.00 - 12.52 = 1.48
The pOH represents the concentration of hydroxide ions, [OH-]. So in this solution, the concentration of [OH-] is 10-pOH:
[OH-] = 10-1.48 = 0.029 M
