GENERAL Notes BIOCHEMISTRY

The exact concentration of NaOH is calculated by using the stoichiometry from reaction to convert the number of moles of KHP used to moles of NaOH and then dividing by the volume of NaOH used to reach the endpoint of the reaction. 1.2.1.2 Equivalent Weight of an Acid In an acid base titration, the equivalence point is the volume of added base where
