CHEM 121 Lab Report 2: Density Determination

Experiment #: 2 Title: Density Determination Purpose: The purpose of this experiment is to learn how to calculate the density of both liquids and solids in the chemistry lab by finding the volume and mass of different substances. Procedure: Density Determination of Water: 1) A graduated cylinder is to be filled with water 2) The temperature is taken using a digital thermometer of the water in the graduated cylinder 3) A value is read and recorded in ºC for the temperature of the water ...

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...
