Lab Techniques and Moles

What you should learn:

IB Chemistry, like all Group IV IB courses, has a heavy emphasis on experimental work. This unit is essential preparation for lab work this year. We will review safety, lab equipment and measurement techniques (sig figs! uncertainty! accuracy/precision! random/systematic errors! error propagation!!) using problems that involve solution calculations. Since most of the chemistry you will do will occur in an aqueous environment (in solution) you must be comfortable calculating molarity, making solutions and dilutions. Additionally, we'll review how to use the colorimeter, providing you with the opportunity to learn how to use an extremely valuable tool for determining unknown concentrations. Using the colorimeter will also give you practice using graphs to say something about a chemical system and understanding how it works will help tremendously in how well you understand the other analytical techniques you will learn this year.

Teacher’s notes

Identify, locate, and know how to use laboratory safety equipment.

Includes aprons, goggles, gloves, fire extinguishers, fire blanket, safety shower, eye wash, broken glass container, and fume hood.

Describe procedures that should be taken in lab emergencies.

  • fire in lab or on a person
  • chemical spills on counter, floor (Distinguish between procedures for corrosive material and flammable material)
  • chemical spill on skin, eyes
  • Gas leak
  • toxic fume inhalation
  • cut skin
  • broken glass
  • unconscious person

Demonstrate basic lab techniques.

  • using analytical balance (tare),
  • obtaining chemicals without contamination,
  • choose appropriate glassware for measuring volume of liquids, conducting reactions (graduated cylinder, beaker, erlenmeyer flask, volumetric flask)
  • Demonstrate proper methods for carrying and moving chemicals and equipment.
  • Use of a colorimeter
  • Check and MSDS for the hazards, precautions and what to do in case of a spill for chemicals you work with.
