Course Description

This introductory chemistry lab course includes experiments involving mass, volume, the nature of substances, density, solubility, graphing, dimensional analysis, empirical formulas, titration, reactions, gas laws, and solutions.

Learning Outcomes and Objectives

  1. The student will apply basic laboratory techniques and procedures by:
    1. properly operating the Bunsen burner.
    2. operating platform and single pan balances.
    3. utilizing common laboratory glassware.
  2. The student will describe and practice basic laboratory safety procedures and will follow all laboratory rules during experimental work by:
    1. following basic laboratory safety rules as set forth by the instructor.
    2. locating laboratory safety and first aid equipment.
  3. The student will describe the physical and chemical properties of commonly used elements, compounds and mixtures by:
    1. distinguishing between physical and chemical properties of substances.
    2. determining physical properties such as density, melting point,boiling point, volume, or mass.
    3. making specific and accurate observations of materials and reactions as to color, odor, energy changes, gas evolution, or precipitation.
    4. recognizing evidence of chemical changes.
  4. The student will make precision measurements and evaluate experimental data through selected quantitative laboratory experiments by:
    1. using a meter stick to measure length of any object in cm, mm, and meters.
    2. reading centigrade thermometers and converting to Kelvin and Fahrenheit.
    3. reading the volume contained in any graduated cylinder in ml and liters.
    4. using a laboratory balance to determine the mass of any object in grams, mg, and kg.
    5. reading the volume of a liquid in a burettes to within 0.02 ml.
  5. The student will make careful observations, reporting, and interpreting of experimental results through selected qualitative laboratories by:
    1. interpreting evidence of solubility and miscibility.
    2. predicting the formation of precipitates based on principles of solubility.
    3. making accurate observations of state, color, and odor of elements,compounds, and mixtures.
    4. distinguishing between elements, compounds, and mixtures.
    5. testing for the presence of oxygen and describing the chemical and physical properties of oxygen.
    6. plotting experimental data correctly using graph paper.
    7. evaluating the evidence of chemical change occurring in a reaction.
    8. determining the relative activities of two metals in a single replacement reaction.
    9. arranging a group of metals from most active to least based upon observations of a series of single replacement reactions.
    10. determining the empirical formula of a compound.
    11. performing chemical reactions to investigate the concepts of stoichiometry, limiting reagent, and percent yield.
    12. determining the end point in a titration experiment, and calculating concentration of solute in an unknown sample.

Criteria Performance Standard

Upon successful completion of the course the student will, with a minimum of 70% accuracy, demonstrate mastery of each of the above stated objectives through classroom measures developed by individual course instructors.
