Challenge Problems
Push your limits with advanced challenges
During a titration experiment, you added 30 mL of 0.150 M NaOH to 25 mL of 0.100 M HCl. Calculate the pH after this addition.
💡 Hint: Use moles calculations and remember to consider total volumes.
You are titrating a weak acid with a strong base. If the pKa of the weak acid is 4.75, what is the pH at the half-equivalence point?
💡 Hint: Think about what happens at the half-equivalence point.
