Good hand written solution with little bit explanation Asap Explain the liquid organic mixes of methanol, 1-propanal, and 1-butanol should be separated, identified and distinguished based on their volatilities. How to find the range of boiling points for the mixture of methanol, 1-propanol, and 1-butanol?
Using the information below, calculate the percentage w/V of lidocaine (MM (234-34 g/mol) in Lignocaine Oral Topical Solution. Show your reasoning clearly and record your final answer to three significant figures. Assay - "Transfer an accurately measured volume of Oral Topical Solution, equivalent to about 150 mg of lidocaine, to a 125 mL conical flask, and protect from atmospheric moisture with a stopper fitted with a tube containing silica gel. Add 20 mL of glacial acetic acid and 2 drops of crystal violet TS. Titrate immediately with 0.1 M perchloric acid VS to a blue endpoint. Perform a blank titration, and make the necessary Lidocaine correction." Results: • Amount of topical solution measured = 7.5 mL Concentration HCIO, = 0.09998 M Volume titrated = 6.99 mL Volume blank titration = 0.65 mL

Take 100ml of the Foam Bath that contains Sodium Laureth Sulphate Cocamide DEA and add sodium chloride solution in incremental amounts whilst stirring, until more than 5% has been added. Note any physical changes that occur during the addition and stirring process.
Using any chemical concept (like concepts in liquid liquid extraction, concepts in recrystlliazation, etc) in an expirment of extraction of Caffein, make a connection to ONE of the following: 1) an event in the news, 2) your career plans, 3) a hobby of yours, 4) another course you are taking, or 5) your personal life.Your writing should find at least one way, if not more, in which the chemical concept you have chosen to talk about is demonstrated in the connection.

A student use the same protocol as in the lab manual to extract 4 chloroanilline, benzoic acid and naphthalene. Below are the steps he took Step 1 - Dissolve all three in 15 ml ether and place in separatory funnel Step 2- Add 15 ml of hydrochloric acid and mix well Step 3 - Isolate the aqueous layer and add sodium hydroxide which resulted in a precipitate Step 4- Add 15 ml of sodium carbonate to the ether layer and mix Step 5- Isolate the aqueous layer and add hydrochloric acid, which resulted in a precipitate. Step 6- dry the ether layer and collect the solid that is left
Suppose you have an organic sample X that is somewhat soluble in water, even though it issomewhat more soluble in dichloromethane or ether solvents. But if you do a singleextraction, you get only 60% of your material to transfer from the water to the organic layer.How many “washes” would it take to extract over 90% of your organic material extracted fromthe water layer?
Why does a solid form at the interface of the two solutions? PROCEDURESynthesis of NylonIn a small beaker dissolve ~ 0.5 mL of sebacoyl chloride in 12 mL of ether. In a smalltest tube get ~ 6 mL (~1/4 of a 6 “ test tube) of 1,6-diaminohexane solution in water.In order to form the good polymer fibers, it is best to not mix the solutions. Youshould try to layer one solution on top of the other. First pour the 1,6-diaminohexanesolution into a 100 mL beaker. Then slowly pour the sebacoyl chloride down the sideof the tilted beaker with minimal mixing. At this point you should see two distinctlayers with a white film at the interface. Hook the nylon which forms at the interfacewith a straightened paper clip and pull slowly straight up as high as possible. Thenwrap it around your large beaker and then continue to wind the polymer around tillthe reaction is complete. Rinse your polymer in DI water to remove any salts or acidthat may be present.Weigh your product and characterize it by…
Each of the solvents given should effectively separate one of the following mixtures by TLC. Match the appropriate solvent with the mixture that you would expect to separate well with that solvent. Select your solvent from the following: hexane, methylene chloride, or acetone. You may need to look up the structures of solvents and compounds in a handbook.a. 2-Phenylethanol and acetophenoneb. Bromobenzene and p-xylenec. Benzoic acid, 2,4-dinitrobenzoic acid, and 2,4,6-trinitrobenzoic acid

The purpose of this experiment is to use both extraction and crystallization techniques to separate a solid mixture of organic compounds. You will receive a packet with 1 g of a unknown (pH is basic) amide solid sample which will contain three components, one from each group: Group 1 (~50% wt): ethyl 4-aminobenzoate, ortho-toluic acid, or benzoic acid Group 2 (~40% wt): fluorene, 1,4-dibromobenzene, benzil, benzoin Group 3 (~10% wt): fluorene, 1,4-dibromobenzene, benzil, benzoin (but not the same as Group 2 compound) Create a lab procedure that will allow you to successfully isolate, purify, and identify the two major (Group 1 and Group 2) components of the unknown amide sample. reagents that can be used are 1M HCl, 6M HCl, 1M NaOH, 6M NaOH, diethyl ether, and methylene chloride
