Chemistry 134
Lab
Course Objective: To provide
students with an explanation of the basic concepts, laws and theories of
chemistry and to apply them to chemistry problems through a laboratory
setting. The student will demonstrate
basic laboratory techniques and be able to apply them in a practical chemistry
setting.
Student Learning Outcomes: Upon completion of this course, the students are expected to

Experiment
17-Kinetics: Determination of the order of a reaction is selected to assess
the outcome. Students are required to determine the order of a decomposition
reaction. They have to demonstrate an understanding of the principles of
reaction rates and apply the correct method according to the lab procedure to
determine reaction order by experiment. Graphic calculators can be used to
help get the best slope for graphs.

Experiment 16- Volumetric analysis: Redox titration is selected to assess the outcome. In this experiment, the titration involves oxidation and reduction reaction. The titrant (reducing agent thiosulfate ion) will be standardized quantitatively, and used to determine the normality of iodine in an unknown sample. Averages and standard deviations of the normality needs to be reported. |

Our
courses present the prevailing scientific theories in chemistry. There are past theories that over time have
been revised because of better instrumentation or knowledge, but there are no
“real” competing theories in chemistry at this level of instruction. Some examples of revised theories are
Bohr’s Theory, Kinetic Molecular Theory, Acid/Base Theory, and
