Titrations starts at 11 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Titrations. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
A 0.0250 mol/L solution of HCl is titrated with NaOH. If 20.0 mL of HCl is neutralized by 25.0 mL of NaOH, what is the concentration of NaOH?
A 0.100 mol/L solution of NaOH is used to titrate 50.0 mL of H2SO4. If 25.0 mL of NaOH is required, what is the concentration of H2SO4?
A student titrates 25.0 mL of HCl with 0.100 mol/L NaOH. If 30.0 mL of NaOH is required to reach the endpoint, what is the concentration of HCl?
A student uses 0.0250 L of 0.150 mol/L H2SO4 to neutralize 0.0500 L of NaOH. What is the concentration of NaOH?
A titration experiment requires 15.0 mL of 0.200 mol/L KMnO4 to react completely with 25.0 mL of FeSO4 solution. What is the concentration of FeSO4 if the reaction is 1:5 (KMnO4:FeSO4)?
A titration requires 40.0 mL of 0.100 mol/L HCl to neutralize 50.0 mL of NaOH. What is the concentration of NaOH?
Calculate the number of moles of NaOH in 25.0 mL of 0.200 mol/L NaOH solution.

Explain the difference between endpoint and equivalence point in a titration.
Explain why a burette is preferred over a measuring cylinder in titrations.
Explain why distilled water is used to prepare solutions for titration.
Explain why it is important to swirl the flask during a titration.
