Please, I need help to do question 7 for the post-Lab questions These is my values obtained in the laboratory : volume of cyclohexanol = 7.39mL ; mass of cyclohexanol = 7.112 g mass of cyclohexanone obtained = 1.535 g Thymol blue = 3 drops volume of Sodium Bisulfite = 1mL volume NaOH used = 20mL Continuation of the procedure 2- Place 0.0700 mol (How many mL would this be?) of cyclohexanol into the RB flask. To it add 6.00 mL of glacial acetic acid. 3- Turn on the stirrer slowly (not the heater!). Make sure the stir bar will not hit the tip of the thermometer. Add 82 mL of a 8.25 % w/w bleach solution (NaOCl (aq)) into the separatory funnel and slowly drip the bleach into the solution at such a rate that the temperature stays between 40-50 °C. The reaction is exothermic and you do not need to heat this reaction with the hot plate. However, do not allow the temperature to go below 40°C as the oxidation would be incomplete.…
Please type all of the parts to this question occordingly to the instructions. Here is an example of a formal procedure based off of the experiment presented in Mohrig:Sodium hydroxide (4.6 g) was dissolved in water (25 mL). This solution was added to a 100 mL round bottom flask along with methyl salicylate (2.0 mL) and a stir bar. The mixture was heated at reflux for 15 min and then progressively cooled to 5 °C. The solution was acidified with 3M sulfuric acid (15-20 mL), and the resulting solid was collected by vacuum filtration. The crude salicylic acid was recrystallized from water to yield ???? g of final solid. The melting point and IR were taken to assess purity. Calculate the molarity of the solution of sodium hydroxide that is used.a. M = b. If the original procedure is the base scale (100%), how far are we scaling down the reaction when using 0.75 mL of methyl salicylate? (Example: the original uses 2.0 mL, if we were to use 1.0 mL, we would be scaling the reaction down…
Following the monograph procedure, a 724-mg of aspirin (MW+180 g/mol) dissolved in 18.5 ml of cold neutralized alcohol. This solution was then initially titrated with 0.101 N sodium hydroxide solution, then later neutralized with 0.104 sulfuric acid. 1. What is the milliequivalent weight consumed by the acidic titrant? a. 1.5392 g-meq b. 2.0907 g-meq c. 1.4948 g-meq d. 2.1528 g-meq 2. What is the milliequivalent weight consumed by the basic titrant? a. 5.8656 g-meq b. 1.5392 g-meq c. 5.6964 g-meq d. 1.4948 g-meq 3. What is the difference of milliequivalent weight consumed in the reaction? a. -4.1572 g-meq b. 4.3708 g-meq c. 0.5515 g-meq d. 4.1572 g-meq
Hi! can anyone here help me to create a schematic diagram about the experiments: " 21. Preparation of Ethyne" by Pdst Chemistry, and "Activity 10: Functional Group Tests for Hydrocarbons" by FRETZ RMT since i dont know what a schematic diagram is, and what processes/contents should be in it. thank you
What impurity was likely removed during the recrystallization necessary and was it effective and why do you think so using the prcedure belwo and the reaction provided. PROCEDURE Synthesis of Dibenzalacetone (A) In this lab you will need to determine the amounts of the reactants you will use. We will use 0.0125 moles of acetone. You need to: (1) convert this into a volume in mL, (2) Calculate the number of moles of benzaldehyde needed based on the balanced chemical reaction, (3) Convert the number of moles of benzaldehyde into volume in mL. Your reagent table should reflect your calculated values. Mix the benzaldehyde and acetone based on the volumes from your prelab calculations in a testtube. Add 25 mL of 10% NaOH solution to a 125 mL Erlenmeyer flask along with a stir bar and 20 mL of ethanol. Make sure the temperature of the solution in the flask is below 25 C before proceeding. Add half of the solution from your test tube to the flask. Allow the solution to…
Direction:A. Create a complete workflow process of producing a Liquid Dosage Form through Extemporaneous Compounding(Laboratory Setting). Use diagrams (boxes and arrows) to signify stepwise and significant procedures. And Provide a one-paragraph description of the workflow by pinpointing the major steps involved in the illustratedextemporaneous compounding. Highlight each step using red. Thank you!!!
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…
