Kris Kelly Gravimetric Analysis Lab CHEM 122L 2/4/08 Background/Theory: This experiment uses a Buchner funnel to separate a precipitate from a solution in a process called gravimetric analysis. A crucible with filter paper ensures that none of the precipitate is lost into the funnel. By attaching a hose and running faucet to the glass nozzle on the funnel, it pulls most of the liquid away from the precipitate. This takes place after the reaction between the dissolved unknown and the acid react. In this case, it is an unknown salt reacting with a Silver Nitrate, to form silver chloride. Therefore, this experiment is the gravimetric analysis of a chloride salt. Key Data: Unknown: B Mass of unknown: 1) .0997g 2) .1477g 3) .1076g Mass of crucibles with filter paper: 1) 24.7970g 2) 22.9417g 3) 24.4285g Molar Mass of AgCl: 143.32g Amount of distilled water in each solution 75 ml Amount of Silver Nitrate added to form initial precipitate 25 ml Results: Mass of AgCl in crucible: 1) .2287g 2) .2500g 3) .3423g
