Challenge Problems

Push your limits with challenges.

Question 1

You have a 0.150 mol dm⁻³ solution of sulfuric acid. If you perform a titration with 20.0 cm³ of this acid using 0.100 mol dm⁻³ sodium hydroxide, how much sodium hydroxide is required to reach the equivalence point?

💡 Hint: Remember to account for the stoichiometry of the reaction.

Question 2

In a back titration scenario, a sample of limestone is added to an excess of hydrochloric acid, and you titrate the unreacted acid with sodium hydroxide. If 0.200 mol dm⁻³ hydrochloric acid is in excess and 20.0 cm³ is titrated with sodium hydroxide and requires 30 cm³ of sodium hydroxide at 0.150 mol dm⁻³. Calculate the moles of limestone reacted.

💡 Hint: Make sure to analyze your data carefully and adjust calculations as necessary.
