Unformatted text preview: Introduction: Quantitative transfer is one that transfers the volume of a solution and all the solute to another container(1). This allows us to perform experiments that require moving substances to different containers and not lose any of the substance that would cause data to be inaccurate. In this lab I quantitatively transfer a solution of KCl from a beaker, to a volumetric flask, and back to a clean beaker while calculating the molarity of the solution in each container. Materials/Methods: I followed the procedures that were given to me(3). The reagents used were of chemical purity and were used as received. All masses were measured using a pan balance. I obtained a 250mL beaker, placed it on the pan balance, and tarred it so the scale read zero grams. Then I added KCl(2.16g, .029mols) to the beaker. I then measured approximately 25mL(25.5mL) of deionized water in a 100mL graduated cylinder and poured the deionized into the 250mL beaker with the KCl. Next I stirred the solution with a stirring rod in order to dissolve the 250mL beaker with the KCl....
