CHEM 116
Chemistry Laboratory II

1 Credit

Description

CHEM 116 is the second lab component of this first-year chemistry course and is taken in conjunction with CHEM 111, its prerequisite or corequisite. The two theory courses, CHEM 110 and 111, as well as two laboratory courses, CHEM 115 and 116, are together equivalent to a six-credit first-year chemistry course. Students are encouraged to take all four courses in order to obtain a transfer credit to another institution. The laboratory courses should be taken in conjunction with the appropriate theory part of the course to be most effective.

The laboratory course is designed so that students will develop observational and manual techniques related to a chemistry laboratory. Each lab session is tied as closely as possible to the theory course so that theory will be demonstrated using analytical procedures. Students will learn how to handle analytical equipment such as balances and spectrophotometers and to set up their own experimental apparatus. Although relatively simple chemical composition and reactions are measured in this laboratory, students will learn the procedures to be followed for developing proven laboratory investigations, such as accurate measurement, record keeping, and experimental design. Some of the experiments include chemical equilibrium, thermochemistry, acids and bases and salts, titration, reaction kinetics, and the determination of constants used in chemical equations. Some labs progress to the study of organic and polymer chemistry.

Delivery Method

This course is offered face-to-face (laboratory, clinicals, practicum) in a laboratory setting.

Prerequisites

CHEM 111, Chemistry II, must be taken prior to or concurrently with CHEM 116 and completion of CHEM 110 and CHEM 115 or equivalent.

Objectives

By the end of this course students should be able to:

• Use laboratory equipment, such as balances, spectrophotometers, glassware, and chemical reagents, with care and proficiency.
• Learn to make observations and measurements clearly and with an appropriate degree of significance, relative to a chemistry laboratory.
• Conduct simple chemical and analytical experiments to determine such properties of chemicals and compounds as solubility products, and interactions, equilibrium reactions, etc.
• Learn techniques in titration analysis and titration reactions for a variety of chemical reactions.
• Learn a simple chemical classification and the properties that determine the groups of chemical compounds.
• Set up and conduct simple experiments to demonstrate chemical reactions and the subsequent calculations for determining chemical constants.
• Carry out experiments that demonstrate some of the properties of different groups of compounds such as the hydrocarbons.

Maximum Completion

1 week

Required Text and Materials

Students are provided with a laboratory manual and other supplies when they attend the lab. For safety reasons, students must wear closed shoes. No open toe shoes or sandals permitted in the labs.

Assessment

Students will receive a final mark out of 100. This mark is determined on the basis of lab attendance and on any lab assignments, tests, or final examinations that are assigned. All lab assignments and the final exam, if given, are at the discretion of the lab instructor. For safety orientation reasons, students are required to attend the first lab session. Students cannot miss more than two lab sessions or an incomplete grade will be assigned.
