organic layer contains the dichloromethane‚ aspirin‚ and the unknown. If the HCl has nothing to react with in the aqueous layer following mixing (i.e.‚ sodium acetylsalicylate)‚ then little to no solid aspirin will be produced. Furthermore‚ more unknown would be produced than expected because aspirin would precipitate with the unknown during distillation. (c) Mistakenly extracting the dichloromethane solution with 5% HCl rather than 5% NaHCO3 would make the solution impure. It would likely not form

moles Moles of HCl in 10ml of 6.0M = 6/1 x 0.01L = 0.06 moles Actual Mole Ratio (AMR) = 0.21/0.06 = 3.5 Equation mole Ratio (EMR) = 1/2 = 0.5 If AMR > EMR then the 2nd reactant‚ i.e. HCl is the limiting reactant and Magnesium is in excess. Hypothesis: Hydrochloric acid will be the limiting react at stages 5 and 6 and Magnesium will be the limiting reactant at stage 7. Procedure: We were given two magnesium ribbons and a beaker of 6M HCl to carry out our

Lab 3: Reaction Order and Rate Laws Name: Student Lab Partners: None Date of Experiment: 16 March 2014 Location: My House Course Number: CHE112 Abstract: When combining compounds‚ there are always two roles considered in the reaction. These are reactants and products. Reactants are the initial compounds before mixing. The products are synonymous with the term byproduct‚ or what remains when the reaction occurs. For example‚ Sodium (Na+) and Chlorine (Cl-)

Abstract: The purpose of this lab is to find the rate law of the reactants and the reactions order. My beginning thought was I would find whole numbers but that would be to easy. My answers were all with decimals. I found that my rate law Is k (HCl)1.36 (Na2S2O3)0.84. I was expecting the solution to change color but I never thought it would turn yellow/white. Majority of my previous experiments have always had darker colors as the outcome like a pink or purple. I was pretty surprised when I saw
