Chemistry Laboratory Report Experiment #28: Hardness of Water Student: Assem Abichshayeva Lab. Partner: Marat Aitkhozha Dr.Brad Logsdon Date: 22.04.13 Purpose: The main purpose of this experiment is to standardize a solution of EDTA by titration against a standard solution made from calcium carbonate‚ CaCO3. Procedure: A 50-mL buret‚ a 250-mL volumetric flask‚ and 25- and 50-mL pipets were obtained from stockroom. The 0.5 g of calcium carbonate was weighted in a small 50-mL beaker.

Proper Use Of Micropipettes A micropipette is one of the instruments that is usually used in science laboratories .Micropipette are used to accurately measure and dispense small volumes of liquid . The capacity of a micropipette can range from less 1µl to 1000µl (1ml) .There are glass pipettes ‚ air displacement pipettes ‚ and positive displacement pipettes . Mostly ‚ the air displacement pipettes and positive displacement pipettes are used . Firstly ‚ the piston is moved to the appropriate
