[(+)-Co(en)3]I3•H2O Preparation
Could you help me understand why this reaction happens for this procedure: dissolve [(+)-Co(en)3][(+)-tart]Cl•5H2O in 15 mL of warm water and add 0.25 mL of concentrated ammonia (15 M) solution. With stirring, add a solution of 17.0 g of NaI in 7 mL hot water. After cooling in an ice-water bath, filter the product using vacuum filtration and wash the crystals with an ice cold solution of 3.00 g of NaI in 10 mL of water. Wash the produce with ethanol and then acetone, air dry [(+)-Co(en)3]I3•H2O.
So how does adding NH3 and NaI convert [(+)-Co(en)3][(+)-tart]Cl•5H2O to [(+)-Co(en)3]I3•H2O. ? pls explain in detail....thank you!

Please help! (These are the instructions I had) 1) Preparation of K2[Cu(C2O4)2] 2H2O CuSO4•5H2O + 2K2C2O4•H2O → K2[Cu(C2O4)2]•2H2O + K2SO4 + 5H2O Heat a solution of 2.5g of potassium oxalate monohydrate in 12.5mL of water contained in a 50mL beaker (approx. 90°C). Heat 1.55g of copper sulfate pentahydrate in 3mL of water to about 90°C and add it rapidly, with vigorous stirring to the hot potassium oxalate solution.

Bromination of Acetanilide In a 25-mL Erlenmeyer flask, dissolve 0.68 g of acetanilide in approximately 4 mL glacial acetic acid. Record the exact amount of the limiting reactant that you used. Add a stir bar followed by 1.6 g pyridinium tribromide. Heat the mixture to ~60°C in a warm water bath for 10 minutes. After the 10 minutes, add 15 mL water and approximately 2 mL saturated sodium bisulfite solution to remove excess bromine, which shows by the disappearance of...

I understand that equivalents is the ratio of the # of moles
of a reactant or reagent compared to the # of moles of the
substrate. But I am confused on how to answer this question and why
the procedure would call for more NaI than Vanillin if Vanillin is
the substance needed substituted. Can you help?
Thanks!
