- On the blank TLC provided to the right, please draw where you would expect to see the spots for B-carotene (lane 1), compound A (lane 2) and compound B (lane 3). This is SiO2 plate and the appropriate developing solvent is used.How will you know that the Volumetric assay reached the Endpoint? Please explain because our prof gave me a picture of Powerpuff girls as supporting learning material. Thank you. I hope u have a great day. <3WHAT IS THE CHEMICAL RECTION FOR THIS PROCEDURE 5-Amino-2-chlorophenol To a 250 mL Erlenmeyer flask containing a Teflon coated magnetic stirring bar was added 85% sodium hydrosulfite (14.0 g), water (80 mL), and 20% (mass/vol) sodium hydroxide solution (16 mL). The mixture was magnetically stirred until a clear solution was obtained, then solid 2-chloro-5-nitrophenol (2.75 g) is added in one portion. The mixture was stirred at room temperature for 20 minutes then heated to a gentle boil for about two minutes during which time the yellow color of the solution disappeared, indicating complete reduction of the nitro function. The reaction mixture was cooled to room temperature and then placed in an ice-water bath for about 10 minutes. The crude product was collected by vacuum filtration, washed with a small volume of ice water and then used immediately in the next step. 4-chloro-3-hydroxyacetanilide The 5-amino-2-chlorophenol was transferred to a 6 inch test tube and water (8 mL) was…
- Can you tell me if I am doing this correctly? For the thermoeter correction, we are given that: literature value of standard - experimental value of standard at end of melting temperature. I found online that the melting range of pure acetanilide is 113-115. From there I calculated the therometer correction. Substance Melting Point Range Begins/Ends (oC) Interval of Melting (oC) Thermometer Correction for Calibration Data (oC) Corrected Melting Point (oC) Crystallized acetanilide Trial #1 111.9 – 112.9 1.0 2.1 Crystallized acetanilide Trial #2 111.0 – 112.3 1.3 2.7 Crude acetanilide 112.9-115.4 2.5 -0.4 Acetanilide standard Lot # 115.6-116.5 0.9 -1.5 N/AI have a Column Chromatorgraphy lab using an alumina, ferrocene: acetylferrocene (50/50 mix) and dichloromethane that yields Benzoic acid > naphthol > Methyl benzoate. Drawing the reactions and reagents that form would be very helpful.What error is introduced into the determination of an Rf value if the top is left off the developing chamber?
- What is inert gas regeneration method?Can you answer this question please according to the prodecure and IR graph Please talk and describe all the details in the IR graph and how pure our substance was accoring to the IR graph 1.063 g of p-acetamidophenol was measured out into a 50 mL round bottom flask along with 8 mL of 1M NaOH in ethanol and a stir bar. This mixture was heated at reflux for 15 min. It was allowed to cool and then 0.80 mL of bromoethane was added to the reaction. The mixture was then heated at reflux for another 15 min. After heating, the solution was poured onto a mixture of ice and water and further cooled on ice and then the solid was collected by vacuum filtration. This solid was then recrystallized from ethanol and water. The final mass of the purified phenacetin was 0.42250 gAnswer within 45 minutes with proper explanation I will give upvote for sure!! Thank you!!
- Summarize the Experimental Procedures(Part A, B, C IN YOUR OWN WORDS AND IN BULLET POINTS: Experimental Procedure for Part B: Place each compound in the first column in a well of aspot plate. If a compound is a solid and not a liquid, add a small amount of water to it and stir.For all solutions, use 0.1 M provided in lab. Use a conductivity device to determine if thesubstance is conducting or not. Record the relative brightness of the light or absence of light. A bright light only indicates more ions are in solution compared to a dim light, not whether it is a strong or weak electrolyte. The concentration of ions must be known to make a more definitive conclusion. The absence of a light indicates that ions are not present. Only the ends of the two copper probes of the device should be in the solution. On the back of theconductivity device is a guide for you to use. Experimental Procedure for Part C: Add approximately 2-3 drops of each pair of reactants in the first column to a test…from this pfd of nitrobenzene production show material balance at mixing -the conversion is 99% and production 1000 ton/dayEnumerate and describe the signs of emulsion instability.
