  • Title: Acid Base Titrations Purpose: In this lab, titration analyses will take place doing six different acid-base titrations. Titration is used to determine an unknown concentration of a substance. Procedure: Experiment 1: Weak acid, strong base Standardization titration was performed to determine the molarity of NaOH (Sodium Hydroxide) by titrating it against a weak acid, Potassium Hydrogen Phthalate. The acid is put in a beaker and phenolphthalein indicator and water is added. Titratio...
