Volumetric Analysis 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 Volumetric Analysis.
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 12
A 0.250 g sample of KHP (molar mass = 204.2 g/mol) is titrated with NaOH. If 15.0 mL of NaOH is required to reach the endpoint, what is the molarity of the NaOH solution?
A burette reading before titration is 0.50 mL and after titration is 25.30 mL. What is the volume of titrant used?
A solution of Fe2+ is titrated with 0.0200 M KMnO4. If 25.0 mL of KMnO4 is required, how many moles of KMnO4 were used?
A student needs to prepare 250 mL of 0.100 M NaCl solution. How many grams of NaCl (molar mass = 58.44 g/mol) are required?
A student titrates 25.0 mL of 0.100 M HCl with 0.100 M NaOH. What volume of NaOH is required to reach the equivalence point?
