Lab 1: Observation of Chemical Changes
Name: Tyler Lee
Lab Partners: none
Date of Experiment: Feb 26 2015
Location: My House
Course Number: CHE111
Abstract:
The point of this lab was to test and observe chemical changes when mixing chemicals together and also through heating chemicals.
Experiment and Observations:
The experiment performed in the first part of this lab was to mix various chemical solutions together and then observe and record the chemical changes, also if a chemical change occurred at all. This was very interesting to me since some of the chemicals I thought were going to react didn’t, while some I thought were going to have no change suddenly changed color or texture.
The observations I made were recorded with the lab manual data table 1 as a guide as to which chemicals to use. A total of eight chemicals were mixed together on this part.
The experiment performed in the second part of the lab was heating 4 different chemical substances (s) and observing the changes made to them. Also determining if a chemical change had occurred. One test was performed with the substances in the tubes and another with the chemicals outside of the tubes and over the open flame.
The observations I made were recorded in the data table 2 and located in the questions section of this lab report.
Data Table 2
Chemical
Initial Observation
Heating Observation
Burning Observation
Mg
Looks like small flakes of silver
Turned bright red and obviously to a very high temp.
Turned bright red and gave off gas
Zn
Much bigger and sturdier than magnesium, although very similar in look (besides size).
Completely melted and then solidified into a new form.
Continued to melt
CuCO3
Green powder
Turned dark black instantly as if it was completely burning
Again turned dark black
Cu(NO3)2
Looked like aqua and navy blue glitter mixed together
Fizzled and looked like it was turning into a gaseous solution
Sizzled, started to turn into gaseous state.
