CH 141 - Lab for CH 140


Credit Hours: 1.0

Topics covered: measurement, physical properties, specific heat and atomic weight, synthesis and gravimetric analysis of compounds, chemical reactions and molecular weight determination of gases. This course satisfies the science requirements for all but liberal arts-science students.

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.
