The Experimental Techniques in Chemistry is an approach to research in which the researcher manipulates one or more variables, and measures any change in other variables. Laboratory and practical courses, where students become familiar with experimental techniques and learn to interpret data and relate them to appropriate theory, play a vital role in chemical education.
