# The Concentration of Hydroxide Ions in an Acidic Solution

## What is the concentration of hydroxide ions in an acidic solution with a pOH of 11.29?

Final Answer: The concentration of hydroxide ions ([OH-]) in the acidic solution is determined to be 1.3 x 10^(-11) M.

## Formula for Calculating Concentration of Hydroxide Ions

**The concentration of hydroxide ions in a solution can be calculated using the formula:**

[OH-] = 10^(-pOH)

## Calculation Steps

**Given:** pOH = 11.29

To find [OH-], we substitute the value of pOH into the formula:

[OH-] = 10^(-11.29)

## Final Answer

Using a calculator, we can evaluate the expression to find the concentration of hydroxide ions in the acidic solution:

[OH-] = 1.3 x 10^(-11) M

Therefore, the concentration of hydroxide ions in the acidic solution with a pOH of 11.29 is 1.3 x 10^(-11) M.
