The pH of a solution is 5.67 at 25 °C. Calculate the pOH of this solution at 25 °C.
Question
The pH of a solution is 5.67 at 25 °C. Calculate the pOH of this solution at 25 °C.
Solution
To calculate the pOH of a solution when you know the pH, you can use the following formula:
pH + pOH = 14
This is because the sum of the pH and pOH of a solution at 25°C is always equal to 14.
Given that the pH of the solution is 5.67, you can substitute this into the formula:
5.67 + pOH = 14
To solve for pOH, subtract the pH from both sides of the equation:
pOH = 14 - 5.67
pOH = 8.33
So, the pOH of the solution at 25°C is 8.33.
