Materials and Methods Animals The Animal Ethics Committee of the Experimental Toxicology Unit from Medical College of Villa Clara‚ Cuba‚ approved experimental protocol. Male and female Wistar rats were used. All rodents and their food were purchased at the National Center of Laboratory Animal Production (Havana‚ Cuba).Animals were kept in specific pathogen–free conditions. Room temperature was 22 ± 2 °C on a 12-h:12-h light:dark cycle. Access to food and water was ad libitum. Sucrose Metabolic Syndrome

Properties of Alcohols and Phenols Experiment #3 Objectives: To observe the solubility of alcohols relative to their chemical structure‚ to perform chemical tests to distinguish primary‚ secondary and tertiary alcohols‚ and a color test for phenol. Introduction The general formula of an alcohol is ROH in which the R is an aliphatic hydrocarbon group. Alcohols may be looked upon as derivatives of water‚ HOH. One hydrogen of water is substituted by an alkyl group‚ R. Like water‚ alcohols show hydrogen

Our data displayed supports the notion that by increasing the acidity of the catalyst‚ the production of aspirin will increase. Our hypothesis was proven correct. In our data‚ we calculated the percent yield and percent error of each trial. We also calculated the average of the percent yields and the percent errors of each catalyst. In the end‚ we saw that for the sulphuric acid catalyzed aspirin‚ we saw an average of 69.7% percent yield and an average 30.3% percent error. As for the phosphoric acid

Name____________________ Comparing Rates of Evaporation Several factors determine how fast a sample of liquid will evaporate. The volume of the sample is a key factor. A drop of water takes less time to evaporate than a liter of water. The amount of energy supplied to the sample is another factor. In this lab‚ you will investigate how the type of liquid and temperature affect the rate of evaporation. Problem: How do intermolecular forces affect the evaporation rates of liquids? Pre-Lab:

Each of the concentrated pigments was dabbed onto their respective rows on each of the three TLC plates using a plastic pipet tip. 3 TLC chambers were prepared using 7mL of each different mobile phase (9:1‚ 8:2 and 7:3 pet ether: acetone solution). The TLC’s were performed and Rf values were measured. All materials were disposed of properly and all glassware was cleaned following correct laboratory
