The objective of the general chemistry laboratory course is to become proficient in techniques used by practicing chemist, to carry out experiments safely and carefully in the laboratory, to obtain data accurately and to manipulate the data correctly. This course also complements and consolidates the theoretical knowledge acquired in the general chemistry lecture course. In as much as this course is only a supplement to general chemistry lecture courses, students must either have had the general chemistry lecture or must be taking the course concurrently.
This laboratory course introduces standard techniques basic to all chemistry laboratories work, such as weighing, filtering, and operating analytical instruments. You will also learn to accurately record scientific data and to derive results from it.
Laboratory experiments include: determination of the atomic mass of zinc and oxygen; Salt crystallization, sublimation of salicylic acid, and distillation of acetone; preparing chemical solutions and titration of acid-base, ox-red; To determine the effect reactant concentration, temperature, catalyst speeds up a reaction; Effect of a common ion on solubility; Perform the exchange reaction.
