titrations

A volumetric analytical method used to quantitatively determine the concentration of a particular

compound in a solution. This technique involves reacting a substance with an unknown concentration with a

standard solution whose concentration is precisely known.

a typical titration is based on the reaction between the titrant and the analyte

A titrant: a solution of precisely known concentration that is carefully added

An analyte: the "unknown" solution for which you would like to know

Equipment:

  • a standard solution of sodium hydroxide (NaOH) with a concentration

of 0.1 M

  • Phenolphthalein: an indicator to show the endpoint of the titration by allowing for a color change.

Equation:

the base is NaOH, and the acid is HCl.
