Abstract: Gas preparation and application are important components of basic chemical experiments, which contains rich chemical experimental knowledge, basic operational skills, scientific thinking and literacy such as chemical principles understanding, device construction, condition optimization, airtightness testing, impurity removal, drying, waste gas disposal, safety risk assessment, and so on. This article focuses on the preparation and purifying of laboratory gases, and proposes standardized operational suggestions for each stage of gas preparation process, thus providing operation suggestions for basic chemistry experimental teaching and practice in middle schools and universities.

Key words: Chemical experiment, Gas generation, Gas purification, Gas collection, Tail gas treatment, Operating suggestions
