metal to form the desired cr(acac), complex. What is the limiting reagent? Calculate your percent yield H2o NH (hydrolysis) H2N H2N NH (deprotonation) Helpful Hints When using a saturated solution to grow crystals, it is important that you filter the solution through a plug of glass wool in a pipet before setting up the crystallization esults. To obtain your EE Rating, you must obtain 50%o yield of Cr(acac)3, and you must produce at least one single crystal that is suitable for X-ray analysis.metal to form the desired Cr(acac)3 complex.
