Laboratory Report for Experiment #5 Titration of Acids and Bases 1 Acids and Bases volumetrical Analysis I. Introduction The place of this experiment was to understand the raw material techniques of titration, solution preparation and volumetric analysis. A fundamental blank space of aqueous solutions is the determination of hydronium ion [H3O+] concentration. The pH of a solution mathematically describes the hydrogen ion concentration [H+], where: (p37) pH = -log [H+] A strong erosive or base in one which is completely (100%) ionise in dilute aqueous solution. A solution containing 0.1 M of hydronium ions (p37) HNO3(aq) -> H3O+ (aq) + II. Procedure: Directions given in the laboratory manual (p40-41) were followed. KHP, NaOH solutions, HCL, and Phenolphthalein were used. III.
