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 11
Define the term 'primary standard' in volumetric analysis.
Describe the role of a burette in volumetric analysis.
Describe the steps involved in performing a titration.
Explain the difference between endpoint and equivalence point in a titration.
A 0.100 M solution of HCl is titrated with NaOH. If 50.0 mL of HCl is neutralized by 60.0 mL of NaOH, what is the concentration of the NaOH solution?
A solution of NaOH is titrated against 25.0 mL of 0.100 M HCl. If 30.0 mL of NaOH is required to reach the endpoint, what is the concentration of the NaOH solution?
