    and along these lines fermentable sugar can be acquired. The glucose arrangement is weakened and changed over to ethyl liquor by the anaerobic activity of yeast, ethanol of 95.6% w/w turns out through parchedness which is concentrated to 99.5% w/w (Ramasamy and Paramasamy, 2001; Kosugi et al., 2009). In this manner cassava-based fuel ethanol is created and it is typically denatured by little volume of fuel or other materials included keeping individuals from drinking it, (Leng et al., 2008). A…

    this experiment is to purify and separate ethanol and water by fractional distillation to achieve the 95% of ethanol and 5% of water; then determine the density of the liquids that were collected. In the experiment, 20 mL of ethanol solution were heated in the distillate flask and maintaining the temperature around 78°C to 82°C until there were 2 mL collected in the receiving flask . The results I observed is that I did not obtain a 95/5 percentage of ethanol and water and my average density of…

    TRIS Hcl, NBT, NADH, Ethanol, PMS, l-ascorbic acid 1. The superoxide radicals is generated in 3 ml of TrisHCl buffer (16 mM, pH 8.0) containing 1 ml of NBT (50 μM), 1 ml NADH (78 μM) and ethanol extract of sample (25 – 50 μg). 2. The reaction was started by adding 1 ml of PMS solution (10 μM) to the mixture. 3. The reaction mixture was incubated at 25° C for 5 min, the absorbance was read at 560 nm using a spectrophotometer (Schimadzu UV-Vis 1700) against blank samples using l- ascorbic acid…

    In this experiment we used the alcohols methanol, ethanol, and 1-propanol, and tested the beet membranes at 0% alcohol concentration, 10% alcohol concentration, 20% alcohol concentration, 30% alcohol concentration, and 40% alcohol concentration. We used 0.5cm3 beet pieces throughout the entire experiment to keep the surface area constant in each alcohol. We then submerged one cube of the beet in each concentration of each alcohol for 15 minutes. We then found the concentration of Betacyanin in…
