The purpose of this lab experiment is to observe physical and chemical properties of substances which are also known as chemicals.
For this laboratory experiment I followed the detailed procedures outline in the Labpaq manual by P. Jeschofnig, LP-0125-CK-01. (Jeschofnig, Peter., Ph.D., "Physical and Chemical Properties." General College Chemistry. Englewood, CO: Hands on Lab Inc., 0. 65-71. Print.) First, I followed all safety measures as outlined therein. After assembling all the necessary supplies and equipment needed to conduct this experiment, I began the lab experiment by identifying physical properties : the color and odor for each substances (a, b, c, d, e, f & g) by observing and smelling each substance then notating my findings. (See excel worksheet which identifies each substance tested in this experiment.) I then added each chemical a, b, c, d, e, f & g separately to a test tube and tested the effect of heat by holding it over a fire source. I observed to see if there was any change in color, conduction of heat or gas. Second, I added each chemical separately a, b, c, d, e, f, g to a test tube and notated the effect of cold water. Third, I added water to each chemical separately a, b, c, d, e, f, g to a test tube and notated the effect of hot water by holding it over a fire source until a boiling point was reached. I noted any observations observed such as bubbling, heat, conduction, gas etc. Fourth, after allowing the solution to cool down from the prior step, I tested the pH of each chemical using red...
