CH 141 - Lab for CH 140

Fulfills SUNY General Education – Natural Sciences.

Course Outcomes
Upon completion of this course the student should be able to:

• use routine lab equipment for the measurement of mass, length, volume and temperature and properly report the results of such measurements to the limit of accuracy inherent in the measuring device;
• handle chemicals and apparatus in such a manner as to insure the safety of the laboratory environment;
• calculate properties of matter from measurements made, using the metric system;
• identify unknowns by determining physical properties such as density, boiling point, flame tests and solubility in various solvents, as well as chemical properties such as flammability and precipitations;
• separate components of a mixture by decantation, filtration and sublimation;
• observe evidence for chemical and physical changes and write balanced chemical equations for chemical reactions;
• distinguish between ionic and molecular compounds on the basis of their electrolytic conductivity, and account for the difference in conductivity between strong and weak electrolytes;
• identify acids and bases on the basis of their most salient properties;
• write electron-dot formulae for simple molecules and ions, and assemble models to demonstrate their structure; and
• use reference materials from library and/or websites to obtain accepted values for properties needed to determine % deviations of experimental results from theoretical values.
