  1. 4.6: Solution Stoichiometry and Chemical Analysis Figure 4.18, P. 139 of text Chapter 4

  2. Titration Terms • Titration: Controlled combination of a solution of unknown concentration with a solution of known concentration • Primary Standard: A relatively pure compound with a • high molar mass • known pattern of reactivity • used as a basis of comparison for the determination of the concentration of an unknown • Secondary Standard: A solution with a molarity that is very accurately known • Standard Solution: A solution of known concentration. Chapter 4

  3. Titration Terms, continued • Equivalence Point: Stoichiometrically equivalent amounts of substances are combined • Indicator: Dyes used to indicate the equivalence point (color change) • Phenolphthalein: colorless in an acid, pink in a base • End Point: the point of color change that coincides with the equivalence point.
