Criticize the following techniques:a. A 100-mL graduated cylinder is used to measure accurately a volume of 2.8 mL.b. A one-piece polyethylene transfer pipette is used to transfer precisely 0.75 mL of a liquid that is being used as the limiting reactant.c. A calibrated Pasteur pipette is used to transfer 25 mL of a solvent.d. The volume markings on a 100-mL beaker are used to transfer accurately 5 mL of a liquid.e. An automatic pipette is used to transfer 10 mL of a liquid.f. A graduated cylinder is used to transfer 0.126 mL of a liquid.g. For a small-scale reaction, the weight of a liquid limiting reactant is calculated from its density and volume.
