Aim To find out how the permeability of a beetroot membrane cell is affected by ethanol. To do this we will investigate different concentrations of alcohol (10-70%) and measure the absorbance using a colorimeter to show us how much juice has leaked out. Hypothesis I predict that as the concentration of ethanol goes up‚ the permeability will increase as the ethanol will slowly dissolve more phospholipids (lipid bilayer) and so more anthocyanin (the beetroot juice) will leak out of the membrane

should be saturated‚ having single bonds to three other atoms.[1] An important class of alcohols are the simple acyclic alcohols‚ the general formula for which is CnH2n+1OH. Of those‚ ethanol (C2H5OH) is the type of alcohol found in alcoholic beverages‚ and in common speech the word alcohol refers specifically to ethanol. Other alcohols are usually described with a clarifying adjective‚ as in isopropyl alcohol (propan-2-ol) or wood alcohol (methyl alcohol‚ or methanol). The suffix -ol appears in the

SUMMARY The aim is to observe distillation process of ethanol-water solution and to measure the alcohol content after process in this experiment. 500 ml of solution with an alcohol content of 32% (v/v) is used for this experiment. Temperature values are recorded for every 10 ml alcohol obtained in the flask. The process is repeated in our experiment and for the first process‚ the data collection process continues until the distillate reaches to 200 ml. The concentration of alcohol is measured for

Bacterial Fermentation Secondary article Article Contents Volker Mu¨ller‚ Ludwig-Maximilians-Universita¨t Mu¨nchen‚ Munich‚ Germany . Introduction Under anaerobic conditions‚ in the dark and in the absence of electron acceptors‚ organic compounds are catabolized by strictly anaerobic or facultatively anaerobic bacteria by internally balanced oxidation–reduction reactions‚ a process called fermentation. In fermentation‚ the organic compound serves as both electron donor and acceptor‚ and adenosine

important that you accurately weigh your sample of acid and titrate to a phenolphthalein (colorless to pink color) end point using an accurately known dilute solution of sodium hydroxide (0.1000 M). If your unknown is soluble in a greater than 50% ethanol/water mixture‚ then use bromothymol blue as the indicator to give a yellow to blue color change. Using an analytical balance‚ accurately weigh out approximately 0.2 g of your unknown acid (measured to 0.001g) and dissolve in 50 – 100mL of water.

Period 1 Group 8 Mrs. Chan Topic: Chemical Explosions Due Date: 9/30/16 For this experiment‚ a few scientists are researching the changes in gas pressure and launch velocity needed to send a film canister across the room using the ignition of ethanol. The independent variable would be the different types of flammable sprays. The dependent variable would be how far the explosions are sent across the room. The constant would be way the device is built for every type of spray‚ and the control would

of this experiment was to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. This was done by mixing the two reactants with NaOH and ethanol‚ then allowing the reaction to sit for thirty minutes. The crystals were then washed with water three times and recrystallized using ethanol. It was then characterized using melting point analysis. The percent yield for this reaction was 59.84%. This was due to loss of crystals during recrystallization and during solvent
