Titrant

Intro to Chemistry

Definition

A titrant is a solution of known concentration used in titration to determine the concentration of an unknown solution. It is typically added from a burette during the process.

congrats on reading the definition of titrant. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. The titrant is always of known concentration and is critical for calculating the unknown concentration in a titration.
  2. In acid-base titrations, common titrants include solutions like NaOH (sodium hydroxide) or HCl (hydrochloric acid).
  3. The volume of titrant required to reach the endpoint allows for stoichiometric calculations to determine unknown concentrations.
  4. An indicator may be used alongside the titrant to visually signal the endpoint of the reaction.
  5. The accuracy of a titration depends on precise measurement of both the volume and concentration of the titrant.
