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