TITRATION

WHAT IS TITRATION?

  • A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. 
  • Typically, the titrant (the know solution) is added from a burette to a known quantity of the analyte (the unknown solution) until the reaction is complete. 
  • Knowing the volume of titrant added allows the determination of the concentration of the unknown. 
  • Often, an indicator is used to usually signal the end of the reaction, the endpoint.
