Jarrett Sears Dr. Hummel Chem 121 2/7/13 A Chemical Reaction between Tin and Nitric Acid Introduction: Finding the products made from the components of tin metal and nitric acid is the ultimate objective of this lab; the formula of the products will be found in the CRC handbook thereafter. Procedure: First, obtain a clean crucible, and heat it under a Bunsen burner until it is as hot as possible, about 15 minutes within a fume hood unit. The Bunsen burner will be used under the fume hood for the entire duration of the lab. Place a crucible on a wire gauge, and wait for the crucible and its lid to cool off completely.After cooling, obtain the weight of the crucible and lid by placing it on a petri dish to be placed on an electric balance (petri dish mass must be obtained prior) without using any hands; there will not be any touching of the fingers or hands to or on the crucible and subtract the mass of the petri dish to obtain the mass of crucible. (Mass is noted at 61. 805g with crucible and petri dish, crucibles mass: 25. 253g) tin is weighed between 0. 9000g and 1.
