Chem 1045 Acid-Base Titration 1 of 6 ACID-BASE TITRATIONS Titration: A method of analysis in which a solution of known concentration is used to determine the concentration of another solution. A titration is just a reaction in which one reactant in solution form is slowly added from a buret to the other reactant until all of that reactant is consumed. The stoichiometry (mole ratio) of the titration reaction must be known. The titration reactions you will be performing are acid-base reactions using NaOH in each case as the base.

Chem 1045 Acid-Base Titration 2 of 6 Part A Standardization of the NaOH solution In order to use the mole ratio between the NaOH and the acid in question, the concentration (molarity) of the NaOH must be known. To find the molarity of the NaOH solution, you will standardize the NaOH by reacting it with a standard solution of HCl – a standard solution is a solution whose molarity is accurately known. Titration reaction: Since there is a 1:1 mole ratio: (M HCl )(V HCl ) =
