Premium Sulfuric acid Water Laboratory equipment
assembled a reflux apparatus in the fume hood with a 100 mL round bottom flask and a condenser. Next we added 44 mL of sulfuric acid to a 125 mL Erlenmeyer flask. We also measured 4.75g ammonium chloride and 8.75g ammonium bromide into a 125 mL beaker‚ crushed the lumps‚ and placed in a 250 mL Erlenmeyer flask along with the sulfuric acid. We used heat to help the solutes dissolve. When they had dissolved‚ we allowed the flask to cool and then poured 17 mL of the solution into a separatory funnel

Procedure: Part A 2.014 g of Panacetin was measured and put inside a 125 mL Erlenmeyer flask. 35 mL of Dichloromethane (DCM) was added to the 125 mL Erlenmeyer flask. After addition of DCM the Panacetin lumps were crushed with a stirring rod. Next a fluted filter paper was pre-weighed. The filter paper weighed around .860 g. Gravity filtration was then used to filter the mixture into a 125 mL collecting flask. The mixture was filtered in order to separate the crude sucrose from the mixture. The

attached to a retort stand on the benchtop and allowed the aqueous and organic layers to separate. (Unlike in typical aqueous/organic separations‚ our organic layer was on the bottom of the separatory funnel.) We cleaned and dried an Erlenmeyer flask‚ and drained the organic layer into the Erlenmeyer by opening the stopcock. We stoppered the Erlenmeyer with a rubber stopper between draining. We repeated the adding of methylene chloride‚ swirling‚ venting‚ settling and draining the organic layer

addition of 4.0 mL cyclohexanol‚ 1.0 mL of 85% phosphoric acid‚ and one boiling chip‚ were all added to a 10 mL round bottom flask that would be attached to the end of an assembled simple distillation set up. A sand bath was placed atop a hot plate‚ and the simple distillation mechanism was lowered into the sand bath with the bottom most piece (the 10 mL round bottom flask) submerged about half way. The distillation process was completed after a sufficient amount of liquid distillate had accumulated

Introduction Chemical reactions don’t typically go to completion. Instead‚ the system goes to an intermediate state where the rate of the forward reaction and the rate of the reverse reaction equal each other. At this point‚ the concentrations do not change with time. These reactions are said to be in equilibrium. Equilibrium is depended on a particular temperature‚ and the concentrations of reactants and products have to follow a rule demonstrated by the equilibrium constant Kc. The equilibrium
