Alec Hildreth 2.4.38 Bryan Ringstrand Mon 5:00 Chemist for Hire: Periodicity Introduction The purpose of this experiment was to determine the position of the three elements on the periodic table. This was done by precipitation with silver nitrate and then filtration using a Buchner funnel. Different groups worked with a different solution, thus obtaining all necessary data to make the required determination Experimental 10 mL of solution A mixed with 10 mL solution X in a test tube and stirred for five minutes. Then the mixture was placed onto a Buchner filtration system where most of the remaining solvent was removed. The filter paper, with precipitate, was then placed
