Questions and Answers

What is the term for the point in titration where the amount of standard is equal to the amount of analyte?

  • Equivalence point (correct)
  • Standard point
  • Titration point
  • Endpoint

    • Why are secondary standards used in titration?

  • Because they are more pure than primary standards
  • Because few compounds can meet the criteria for primary standards (correct)
  • Because they are easier to prepare than primary standards
  • Because they are less expensive than primary standards

    • What is the primary standard in titration?

  • A purified compound that is used as a reference (correct)
  • A highly corrosive substance
  • A reagent of unknown concentration
  • A substance that is highly reactive
