Course Code: CHE026L Laboratory Activity Sheet #2 Name: Group number: Section: Schedule: Date: _ ACTIVITY NO.2 LABORATORY APPARATUS AND EQUIPMENT Learning Objectives At the end of the activity, you should be able to:  To be able to identify the various laboratory equipment and apparatus.  To be able to use appropriate laboratory equipment and apparatus during an experiment. Materials:  Pen, Paper/Bond paper Introduction: Chemistry, like any branch of science, is quantitative and experimental. Students will spend a lot of their time in the laboratory investigating and identifying chemicals present in a compound or solution. It is a place where they will test hypotheses, observe and make inferences or generalizations as they explore the experiments. Laboratory apparatus and equipment are the tools required to complete laboratory work. There are seven classifications of laboratory apparatus and equipment and these are the (1) measuring type, (2) reaction type, (3) vessel type, (4) separation type, (5) solid clamp type, (6) heating type, and (7) matching type. Measuring type is mainly used for measuring quality, volume, temperature and density and mostly are glassware, including measuring glass, transfer pipette, measuring cylinder, measuring cup, and etc. Reaction type is mainly used for chemical reaction, also includes a part of heating lab equipment, mostly are glass or porcelain equipment. It includes test tube, flask, evaporating dish, crucible, etc. Vessel type are mainly used to contain or store solid, liquid, gas and chemical reagent, such as reagent bottle. Separation type is mainly used for filtration, liquid separation, extraction, evaporation, firing, crystallization, fraction, including funnel, separating funnel, evaporation dish, flask, condenser, crucible, beaker, etc. Solid clamp type is mainly used to fix and clamp all kinds of chemistry lab equipment and fitting, including iron clamp, iron ring, iron stand and funnel support. Heating type is mainly used for heating chemistry lab equipment and fitting, including test tube, beaker, flask, evaporating dish, crucible, etc. Matching type is mainly used to assemble and connect set of apparatus or equipment like glass tube, glass valve, rubber tube, rubber plug, etc. This document is the property of PHINMA EDUCATION  Course Code: CHE026L Laboratory Activity Sheet #2 For these activities or objectives to be realized, the laboratory is equipped with the different apparatus and equipment. Proper handling and proper use of each apparatus or equipment is necessary for safety reasons. Awareness and practice of the procedures and precautions are also important for students to follow. Procedures: 1. Research on different apparatus and equipment generally found in the laboratory. 2. On a clean sheet of paper / bond paper (short or long), draw five examples of laboratory apparatus and equipment for each classification and give the name, physical description, and uses or functions for each. Refer to the ACTIVITY SHEET for the format. 3. Answer the ACTIVITY QUESTIONS.
