The final product of this reaction, [Cu(NH 3) 4]SO 4 H 20 is soluble in water. What will you add to the solution after you add the concentrated ammonia to cause this product to precipitate out of solution? 95% ethanol methanol isopropyl alcohol Nothing will be added. The precipitate will form when the solution is cooled in an ice bath. Nothing will be added. The precipitate that we will isolate will form as the concentrated NH3 is added to the solution of [Cu(H₂O)4]²+ QUESTION 6 You will isolate the [Cu(NH 3) 4]SO 4 H 20 product before you leave the lab on Day #1, but you will not weigh your product to determine the yield until Day #2. Why is it necessary to wait until the next lab period before you weigh the product to determine the yield? This is a long experiment, and there won't be time to weigh the product before class ends on Day #1. We wait to weigh the product to allow time for any water and/or ethanol to evaporate completely. If the product is "wet", the measured yield will be too high. ○ It will take several days for the solid to precipitate after we add the ethanol. It is not necessary to wait several to determine the yield. The mass of product isolated can be determined on Day #1.

I had 1.0 mL of 1.0M CoCl2 in a test tube. I put it into boiling water. [Co(H2O)6]2+, [CoCl4]2- Equilibrium temperature effect. Effect of heat What happens to the equilibrium? Use this equation in your explanation... 4Cl_ (aq) + [Co(H20)6]2+(aq)---[CoCl4]2-(aq)+ 6 H20 (l) I did this in class. The color change was very slow but it changed from a burgandy to fushia.
please help with this question. it's not an assay, but calculation. thanks
