How would you prepare 75 mL of an H2SO4 solution at 20% in weight (density=1.1394 g/mL, richness=227.9 g/L) starting from the commercial H2SO4 solution (98%, density=1.8361 g/mL, richness=1799 g/L)? Please choose among the most appropriate procedure which better describes the preparation of the previous diluted H2SO4 solution: Select one or more: a. Take the required volume of commercial H2SO4 solution with an adequate pipette, pour it into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently. b. Take a beaker and put about 40 mL of distilled water. Then take the required volume of commercial H2SO4 solution with an adequate pipette and pour them over the beaker. Let the solution be warm and pour the mixture into a graduated flask and add water up to the final volume (75 mL in this case). Homogenize the flask by stirring it gently. c. Take a beaker and put about 40 mL of distilled water. Then take the required volume…

10g coffee 4g sodium carbonate 40m dichloromethane 160ml distilled water coffee filter What are the principles behind caffeine being extracted from coffee using the above items? 1st sodium carbonate mixed with coffee then brought to a boil for 20min then solution/grinds are filtered. Then solution is added to a separatory funnel with 15ml of dichloromethane and two layers are observed so the bottom layer with DCM contains the caffeine, then this layer is collected in a beaker and dried out using molecular seeds. Then the solvent is brought to a boil with crude caffeine remaining and recystallized using 95% ethanol and brought to a boil again. Then the contents are vaccum filtered and allowed to dry resulting in 30mg caffeine.
