Experiment #10 Volumetric Analysis The Titration of Acids and Bases Purpose This experiment will allow you to gain practical experience in the preparing standard solutions‚ using a pipette and a buret‚ and performing standard titrations. You will use this experience to experimentally determine the concentration of acetic acid in an unknown solution. There are three parts to this experiment‚ they are 1. Preparation a standard solution of oxalic acid (~0.07 M) 2. Preparation a sodium

INTRODUCTION Differences between acids and bases An acid-base reaction is based on the reaction involving the ionization of water H2O -> H+ + OH- This means that water can break apart into a hydrogen ion and a hydroxide ion. These two ions can also join together to form a water molecule. When a strong acid is placed in water‚ it will ionize completely‚ and break down into its constituent ions in which one of it a hydrogen ion. When a strong base is placed in water‚ it will ionize

acid‚ which translates into a 0.87 mol/L concentration of acetic acid. The concentration of acetic acid in the vinegar sample should be the same. Purpose: If we add acid solution to basic solution to produce water and salt this activity is called titration. It involves carefully adding one solution to another until chemically equivalent amounts react. Vinegar is a solution of a weak acid in water. This acid will react with the base sodium hydroxide in a 1:1 molar ratio. If a solution of NaOH of known
