Practice Questions
Test your understanding with targeted questions related to the topic.
Question 1
Easy
What is pOH if [OH−] is 1 x 10^-2 M?
💡 Hint: Use the formula: pOH = -log10[OH−].
Question 2
Easy
If a solution has a pOH of 6, what is the concentration of hydroxide ions?
💡 Hint: Recall that [OH−] = 10^-pOH.

Challenge Problems
Push your limits with challenges.
Question 1
A solution has a pH of 11. What is the concentration of hydroxide ions, and what is its pOH?
💡 Hint: Start by finding the pOH and then use that to find hydroxide concentration.
Question 2
If a solution with pOH changes to 9 due to dilution, what was the original pH?
💡 Hint: Use the relationship pOH + pH = 14 to find the initial pH.
