I. Introduction

Chemicals have been indispensable in the everyday lives of humans. Their uses have made life easier and better. However, their effects on the environment have been accumulating and can’t be ignored. The different hazards and biochemical effects of chemicals must be given proper attention and should be addressed appropriately. If not addressed properly, they may cause disturbance of the balance of the environment and ecosystems they may have contact with. Thus, various measures are being intensively applied to address such effects. One of the sources of chemicals in our environment is the laboratories. These may be in industry, medicine, research or in schools and universities. In this report, we specifically looked on to the chemical waste treatment and disposal of CHEM 111.1 Physical Chemistry Laboratory in the University of the Philippines Los Baños. In this laboratory, the basic principles of chemistry are discussed including chemical thermodynamics, properties of gases, and physical and chemical equilibria. The following are the titles of the exercises performed in each semester of the laboratory class:

* Exercise 1: Molecular Weight Determination by Vapor Density Method * Exercise 2: Computation of the Compression Factor and Fugacity of Real Gases * Exercise 3: Joule-Thomson Experiment
* Exercise4: Vapor Pressure of a Liquid
* Exercise 5: Enthalpies of Reaction
* Exercise 6: The Acid Dissociation Constant of an Indicator Dye * Exercise 7: Surface Tension of Pure Liquids And Solutions * Exercise 8: Viscosity of Pure Liquids And Solutions

It must be emphasized that the nature of chemical wastes generated in...
