MAKE A METHODOLOGY : MATERIALS/ REAGENTS WITH SCHEMATIC DIAGRAM . THE PICTURE UPLOADED SERVES AS A GUIDE, DO THE SAME THING BASED FROM THE PIC. Procedure: Place 20 drops of each of 0.2M CuSO4 in a centrifuge tube. Then add 5 drops of freshly prepared 6M (NH4)2S to each centrifuge tube. Record your observation. Centrifuge the mixtures for 3 mins. and decant the supernatant liquid. Add 10 drops of DI water and 10 drops of 6M HNO3. Stir and boil the mixture in a hot water bath for 5 mins. centrifuge the mixture for 3 mins. Decant the supernatant solution from procedure 3. Discard the To each of the supernatant liquid, add 6 drops of 6M H2SO4. Allow themixtures to cool and 5 drops of DI water. To the mixtures in procedure 4, add few drops of concentrated NH3 until the solution becomes basic. Confirm using a litmus paper. Record your observation. Add 1 drop of 5M NaOH and 1 drop of 0.1 M SnCl2 to the centrifuge tube containing Bi3+ ion , centrifuge and decant the supernatant liquid. To…
A student rushed through this experiment. Describe the effect that the following procedural changes would have on the percent recovery of acetanilide. Briefly explain the basis of each answer.(a) Rather than adding 0.5-mL portions of boiling solvent to the acetanilide, the student added 5-mL portions of boiling solvent.(b) The student did not pre-heat the gravity filtration apparatus.(c) The student forgot to cool 5 mL of solvent in Part 5 and washed the crystals with room-temperature solvent.
What is/are the limiting reagent(s) for this three-step procedure? Why is sodium borohydride not the limiting reagent even though a smaller number of moles of this reagent are used? Mass/volume used in experiment: O-vanillin = 0.760g P-toluidine = 0.535g Ethanol = 15 ml Sodium borohydride = 0.1 g Glacial acetic acid = 2 ml Acetic anhydride = 2 ml

Find out the volumes required to produce 0.025 mol of the dibenzalacetone (product). Make sure to use 2.2 : 1.0 molar ratio of benzaldehyde and acetone respectively. This is to ensure that benzaldehyde is in excess, and the acetone is the limiting reactant
Melting point: 98-105 Percent yield: 60% did you successfully make pure product? Explain.
1.Each of the student statements below is wrong. You will need to explain why they are not correct. (a) All my compound dissolved right away in the small amount of solvent I added at room temperature, and I didn’t need to heat it at all. This means I’m going to get lots of pure compound out. (b) I did a recrystallization of naphthalene and my percent recovery was very high (99%), so I must have pure product. (c) When you’ve dissolved all your compound in hot solvent, and you’re in a hurry, it’s ok to just place it straight into the ice bath.
Please answer the question at the bottom, Thanks. LAB NOTES FOR PREPARATION OF BUTYL MAGNESIUM BROMIDEAND ITS SUBSEQUENT CONVERSION TO AN ALCOHOL To the reaction flask were added 2.5967 gram of magnesium turnings, about 20 mlof diglyme, and a solution of 13.5942 gram of butyl bromide in about 25 mldiglyme.The procedure as per the lab manual was initiated. After the required heating timewas completed the reaction mixture was allowed to cool to room temperature.Then a solution of 6.1123 gram of acetone in about 15 ml of diglyme was addeddropwise as per the lab manual.The rest of the lab manual procedure was completed, ultimately affording 2.5532gram of an oily, clear and slightly yellow liquid, presumed to be 2-methyl-2-hexanol. Boiling point as measured by distillation was 138 – 141 deg C.About 0.8 ml of the presumed 2-methyl-2-hexanol was placed in an NMR tube towhich was added 2 drops of TMS. The tube was capped, then inverted and righted20 times to thoroughly mix the product and…
