CREATE A SCHEMATIC DIAGRAM USING THE PROCEDURE: Weighing of standard reagents 1. Make an improvised weighing dish for solid samples (i.e. aluminum foil). Put the foil inside the analytical balance. 2. Press TARE. 3. Weigh accurately 0.4000 grams of NaCl powder in the foil. The reading of the weight must not exceed + 0.0030 g. Note that unused or excess chemicals should never be returned to the stock bottle. 4. Close the balance glass door. Note the actual weight of the NaCl powder that is reflecting on the analytical balance. 5. Transfer carefully the contents in a 150-ml beaker.

Pinacl-Pinacole lab What visual criterion is to be used to assess whether the crude reaction product is dry prior to semimicro distillation?
The experiment wAs preformed using a recrystallization of salicylic acid. The IR was preformed using a KBR pellet method Re-state the diagnostic peaks from the results, this time with the intention of comparing the experimental to literature diagnostic values as well as fingerprint regions to provide evidence to answer your hypothesis. After comparing your values, you must discuss what conclusions you obtained (i.e. was there evidence to support that your compound is pure?)
What could have gone wrong in the separation and purification process to result in the disparity from the observed and expected yields? Select all that apply A) Both the benzoic acid and sand may have been wet before the student recorded the masses, hence the increase in expected masses. B) The student may have filtered the benzoic acid while cold. Hence the sand could have been contaminated with benzoic acid and resulted in a higher mass for sand. C) The sand may have dissolved in the hot water along with the benzoic acid, hence, the recorded mass for benzoic acid was more. D)The benzoic acid may have been cooled down too quickly on ice thereby allowing other soluble impurities to crystallize with benzoic acid causing the increase in the expected mass
Which of the following could result in a loss in yield in a mixed solvent recrystallization? i. Use of fluted filter paper in hot filtration ii. No heated solvent in the receiving flask iii.Rapid cooling iv. Both ii and iii
Earth, a CHEM 40.1 student, extracted a mixture of pigments from the roots of Rubiatinctorum, commonly known as rose madder. Earth spotted the root extract on twohydrophobic silica gel plates. He then placed each plate in separate developing chambers,one containing solvent system WHITE and the other housing solvent system MIX. Earthallowed the chromatograms to develop for around five minutes. Afterwards, he removedthe plates from the containers and placed them inside an iodine chamber. Thechromatograms resulting from the TLC experiment after visualization are illustrated asfollows. The distances travelled by each spot and by the solvents were measured andrecorded in the displayed table.
Extraction of the aqueous salicylic acid solutions with 10% ethyl acetate/hexane (density ~ 0.7 g/ml) will give two layers in the separatory funnel. a. Will the aqueous layer be the upper layer or the lower layer? b. If dichloromethane (density ~ 1.3 g/ml) were substituted for the 10% ethyl acetate/hexane solution, which layer would be the aqueous layer?
State why calibrators and control for analyzers should be purchased in addition to the reagent?

In an EAS Reaction the compounds 5.0g of acetanilide, 0.2g potassium bromate, 5ml acetic acid, 0.9 ml hydrobromic acid solution, and 5 ml saturated sodium bisulfite solution are used. Given these compound and obtaining a yield for the experiment at 6.3 grams which yields 5.3 grams after recrystallization and drying, Please find the theoretical yield and the percent yield?
In an experiment the essential oils from herbs, were extracted with water. Explain how you will separate the oils from the water using liquid-liquid extraction. Discuss the procedure, equipment and extraction solvent choice
How will you increase the measured yield of recrystallized benzoic acid? The receiving flask from hot filtration should not contain a little amount of solvent. Activated charcoal was not introduced to the solution. During cold filtration, a fluted filter paper was used. After hot filtration the solution was filtered immediately.
A student properly sets up a column chromatography experiment. Although the mixture is soluble in the mobile phase, the sample appears "stuck" at the top of the column and will not elute regardless of how much solvent is applied. What could be the cause of this problem and what could the student do to try and achieve a successful separation?
