Give two reasons why the product was washed with acetone instead of water
Add -1 ml of dilute hydrochloric acid to the test tube containing the water. Record your observations. I Report The first section should have the overall reaction(s) and a table that lists the mass and number of moles of CusO, the theoretical number of moles of product, the theoretical mass of product (theoretical yield), the actual mass of product (experimental yield), and the percent yield. Show the calculation you used to determine the percent yield In a second table, provide the results of the solubility tests you performed. In a sentence or two describe what happened when you added HCI to the agueous solution of your complex ion. Answer the following questions. Give two reasons why the product was washed with acetone instead of water. Predict whether each of the following would result in a higher, lower, or unaltered percent yield of product. Explain each answer with a brief sentence or two. a. The product was washed with water instead of acetone. b. Not all of the acetone was removed in the drying step. c. The beaker was not rinsed with the additional 5 mlL of ethanol. d. More than 10 mL of water was used to dissolve the anhydrous copper(II) sulfate. What color was the filtrate (the liquid that was left in the filter flask after the vacuum filtra- tion and washings)? What implications does this have with respect to your percent yield? Are there other steps in the procedure that might have affected your percent yield? 1. 2. 3. 46
