Performing Titration Analyses for Water Quality. Module 17. Vocational Education Training in Environmental Health Sciences.
Consumer Dynamics Inc., Rockville, MD.
This module, one of 25 on vocational education training for careers in environmental health occupations, contains self-instructional materials on performing titration analysis for water quality. Following guidelines for students and instructors and an introduction that explains what the student will learn are three lessons: (1) naming each part of the titrating apparatus and telling how each works or is used; (2) getting the titrating apparatus ready for use by putting it together and by cleaning the buret; and (3) reaching the endpoint of a titration to standardize the titrating solution, sodium thiosulfate. Each lesson contains objectives, recommended methods and locations for practice, performance criteria, equipment and supplies to perform a task, detailed step-by-step instructions for learning a task, and performance exercises. Two performance tests cover preparing the titration apparatus and doing a titration to standardize the titrant.
