Experiment N | Kinetics of the Depolymerization of Diacetone Alcohol via Basic Catalysis | | Ingrid Tafur -5672578 | 2/11/2011 | CHM233O Partner: Laura Marrongelli Demonstrator: Cheryl McDowall Objective The rate constant of the depolymerization of diacetone alcohol via basic catalysis was determined by monitoring the change in volume as a function of time at constant temperature of a pseudo first order reaction where the species in excess was sodium hydroxide. This was accomplished

Different mass of calcium carbonate reacting with hydrochloric acid will change the mol of reactant. It will be affecting the rate if it becomes limiting reagent. I am always going to use 3.00g of calcium carbonate weighed on the electronic balance. Ensure calcium carbonate is pure supply‚ not contaminated. Surface area of CaCO3 The surface area of calcium carbonate should be kept constant. Different

School of Chemistry @ Pietermaritzburg University of KwaZulu Natal Chemistry 310 Substitution reaction of Molybdenum Hexacarbonyl: the use of infrared spectroscopy as a structural tool in metal carbonyl chemistry. Abstract The synthesis of isomer A and B of [Mo(CO)4(PPh3)2] were prepared from molybdenum hexacarbonyl‚ sodium borohydride and triphenylphosphine with a % yield of 79% and 8.5% respectively. Two isomer was identified using IR spectra and from isomer A four C≡O stretching

the formation of a precipitate. Materiel needed: Test tubes Rack of test tubes Plastic droppers Beakers Procedure: We prepare 7 beakers of 7 different solutions (that we mark from 1→ 7). We put separately around 50 ml of: HCl NaOH Na2CO3 K2CrO4 CaCl2 CuSO4 Unknown substance Using plastic droppers we mix 10 drops of one solution with 10 drops of another solution in a test tube‚ to get all in all 20 different test tubes. We then note the observation for each test tube. Name
