You will be giving a mixture containing iron, salt and sand. Your job is to figure out how we should separate these three components into their pure, uncombined forms. In order to successfully complete the lab, you must recover all three components. In other words, when you are done, I will need to see three piles: one iron, one salt, and one sand. Your first step is to write a procedure. No lab work may begin until this procedure is approved by your teacher. If you are wondering what supplies you may use, you may assume that any of your basic chemical supplies will be available. If you feel that you need some equipment not usually found in a lab, ask your teacher if such equipment would be made available. Lab #9: Periodic Table: “Families” Background: We continue our look at the patterns in the periodic table. In this activity, we will be observing chemical reactions to see if there are any patterns in when they occur. Materials: Well Plate Magnesium solution Calcium solution Sodium carbonate solution Barium solution Silver Nitrate (AgNO3) (Na2CO3) Chlorine solution Bromine solution Iodine solution Procedure: Part One: 1. Place several drops of each chemical (excluding silver nitrate and sodium carbonate) in your well plate. As you place each chemical in its well, make sure to mark the position of that chemical. 2. Add several drops of sodium carbonate to each of the chemicals. Records your observations in your periodic table “data table” by placing a dot in each block where a reaction occurred. In the space below, write down your general observations. In other words, if chlorine reacted with sodium carbonate, I would find the square on the periodic table that represents chlorine and I would place a dot in it.
