Questions and Answers

What is the primary purpose of volumetric analysis?

  • To accurately determine the amount of a substance experimentally (correct)
  • To create a chemical reaction between substances
  • To determine the physical properties of a substance
  • To mix different substances thoroughly
  • In a solution, which component is present in the greater amount?

  • Neither, both are solid substances
  • Solvent (correct)
  • Both are present in equal amounts
  • Solute
  • What is the role of the known concentration solution in volumetric analysis?

  • To determine the volume of the solvent
  • To react completely with an unknown concentration solution to find its concentration (correct)

    Volumetric Analysis

    A method to determine the amount of a substance using the volume of a solution with a known concentration.

    Solution

    A homogeneous mixture where one substance is dissolved in another.

    Solute

    The substance present in a smaller amount in a solution.

    Solvent

    The substance present in a larger amount in a solution.
