Volumetric Chemical Analysis
Conditions of Use:
No Strings Attached
Rating

Analytical chemistry is the branch of chemistry that deals with determination of qualitative and quantitative information about matter. This module covers introductory topics that are fundamental to analytical chemistry and it will mainly focus on quantitative aspects of reactions in aqueous solutions, termed solution stoichiometry. Volumetric chemical analysis which include various types of titration such as: acid-base, complexometric, redox, and precipitation titrations, will be examined in detail. In addition, a review of the basic concepts of chemical equilibria and specifically, acid-base equilibria will also be treated. As a prelude to all the topics mentioned, the concept of reliability in quantitative measurements such as sampling procedures, uncertainty as well as statistical treatment and presentation of experimental results will be discussed.
