h Lab Report Katelyn Gularski (Hayly Stein) PM Tuesday 9/9/14 Introduction The purpose of this lab was to separate the mixture of salt, sand, and shells, so that each could be individually massed and the percentage-by-mass could be determined. The best way to get the sand and shells by themselves is to get rid of the salt. Since salt is dissolvable in water, you use water solubility (Hallows, 2014). Water solubility is defined as a substance being able to completely…

The choice of solvent is of utmost importance in a recrystallization so three small scale recrystallization “pilot” experiments will be carried out prior to purifying a larger amount of material. For these experiments acetone ethanol and hexane will be tested as possible solvents for the bezanilide-thiourea crude mixture. The desired solvent will dissolve the impurity (thiourea), and partially dissolve the compound to be purified (benzanilide) so that when heated, the…

There are several different reactions that can be utilized in order to end with a product that includes the synthesis of carbon-carbon bonds, however for this experiment the reaction that was utilized is aldol condensation. An aldol condensation is when an enolizable aldehyde or ketone undergoes a reaction, in the presence of a base or acid, and gives a beta unsaturated ketone or aldehyde (Utah Valley University, 2009). This type of reaction can also add carbonyls to a compound, using similar…

Treat stains on bluestone using the following methods: Oil-Based Stains - Apply ammonia, mineral spirits or acetone. Organic Stains - Spray the area with a 12% hydrogen peroxide solution. Rust - Purchase and apply a poultice from your local hardware store. The poultice may need to rest overnight. Ink Spots - Use bleach or hydrogen peroxide on light stone. Apply acetone to darker stones. Paint - Lacquer thinner will remove small spots. Use commercial paint stripper for large…

401(a) the acetone does have a tendency make a fact more or less probable without the evidence. The acetone give the prosecutor strong evidence against the defense because of the cause of the fire. Rule 403 – The judge can consider the following in application of the Rule 403. The acetone is damaging evidence. 3. Storm's arson conviction from 2001: Rule 609 – Prior Conviction 609 (a)(1)(B) – The…

Identifying an Unknown Compound Using Various Chemical Analysis Techniques Joshua Nash and Aquilla Young Abstract The introduction of this lab report exposes the reader to the different scientific concepts that are to be used such as melting point calculations, retention factors, and solubility in various aqueous solutions. The experimental provides the basics of using a melting point apparatus, determining solubility, and performing thin layer chromatography. In the results section the findings…

FTIR analysis of the stem bark extracts of Cassia fistula has absorption bands and the wave numbers (cm-1) of the prominent peaks obtained were described in Table 2. The peak at a frequency of 3463 cm-1, 1618 cm-1, 1448.3 cm-1 and 1241.9 cm-1 were strong while the others vary from medium to weak. Discussion: Phytochemical studies revealed the presence of secondary metabolites like tannins, flavonoid, carbohydrate, saponins, glycosides and phenol in the leaf extract while tannins, flavonoids,…

Alcohol with the concentration levels of 10%, 20%, 30%, and 40%. The third chemical tested was Acetone with the concentration levels of 10%, 20%, 30%, and 40%. The fourth chemical that was test was 30 percent of ethyl alcohol with concentration levels of 10%, 20%, 30%, and 40%. SDS breaks down the cell membrane the most compared to the other chemicals. Alcohol doesn’t break down cell membranes that well. Acetone is also a weak chemical or disrupting cell membranes. Lastly, 30 percent of ethyl…

know exactly how many chemicals are in electronic cigarettes, there have been 42 identified (Harmful Chemicals in Electronic Cigarettes). Out of the 42 identified chemicals, there are certain ones that are especially harmful such as acetaldehyde, acetone, cadmium, lead, and nicotine (Harmful Chemicals in Electronic Cigarettes). Besides these dangerous chemicals, there are others that emit second-hand smoke. These chemicals include Benzene, diethylene glycol, formaldehyde, isoprene, nicotine,…

In this reaction, acetone was used because it is a polar aprotic solvent, meaning that it has no –OH or –NH groups. Polar aprotic solvents increase the SN2 reaction rate by surrounding the accompanying cation and therefore, raising the ground-state energy of the nucleophile…
