Q
Q: If the pH of a solution is 11, what is the concentration of hydroxide ions [OH-] in the solution?
Solution:
pOH = 14 - pH = 3, [OH-] = 10^-3 M.
Steps: 7
Show Steps
Step 1: Understand that pH is a measure of how acidic or basic a solution is.
Step 2: Know that pH + pOH = 14. This means if you have the pH, you can find the pOH.
Step 3: Since the pH is given as 11, calculate the pOH by subtracting the pH from 14: pOH = 14 - 11.
Step 4: Perform the calculation: pOH = 3.
Step 5: Now, use the relationship between pOH and hydroxide ion concentration: [OH-] = 10^(-pOH).
Step 6: Substitute the pOH value into the equation: [OH-] = 10^(-3).
Step 7: Calculate the concentration: [OH-] = 0.001 M or 10^-3 M.
