Vauh section. UL LUMPale di Conec For this lab you will once again have three separa once again have three separate sets of calculations: PARTI - Synthesis and purification of [Cu(NH3).J$0. i. limiting reagent determination (use the reactant) nt determination (use the stoichiometric ratio to determine the limiting CuSO4.5H20 (s) + 4NH: (aq) → [Cu(NH3)4]S04.H20 (aq) + H20 (1) ercentage yield of crude product (remember to include the 0.025 g of compound you take for determining the absorption spectrum). actual...
Pre-Lab Assignment 1) Draw the reaction mechanism for the reaction. 2) Determine the limiting reagent. Procedure 1 Place approximately 1 g of stilbene dibromide prepared in last week's experiment in a 50 mL round bottom flask. Record the exact mass. Add 0.8 g of KOH and 4 mL of triethylene glycol from the syringe provided in the fume hood (rinse any crystals from the sides of the flask while adding triethylene glycol). 2 Heat the stirred reaction mixture to a...
