Preparing Dilutions of the Silver Nanoparticles 1. Gather all materials. 2. Put on a pair of disposable gloves. 3. Make a paper towel damp with some 70% isopropyl rubbing alcohol. Wipe down the work surface with the rubbing alcohol-dampened paper towel. 4. Using a permanent marker, label the five baby food jars #1 to #5. 5. Using the 25 milliliter (mL) graduated cylinder, measure and pour 22.5 mL of distilled water (from a new, unopened container) into each of jars #2, #3, #4, and #5. 6. Using…

Experiment 2. Steam Distillation The Isolation of the natural product trans-cinnamaldehyde from Cinnamon bark Abstract: This experiment aims at separating cinnamaldehyde from the cinnamon bark. A mixture of volatile and non-volatile elements is separated through the steam distillation method with temperature being below 100 oC. Moreover, the method is used to extract essential oils. The cinnamaldehyde will be conveyed up with the distillate, observed as an emulsion on the condensed vapor. It…

reduces pain and inflammation by limiting certain hormones. The drug is taken orally, usually in the form of a pill, and is absorbed into the bloodstream once it dissolves. Both human saliva and human stomach acid aid in dissolving the pill. Human saliva has a pH of about 6, and stomach acid has a pH of approximately 2. The purpose of this investigation is to discover whether the pH of a solution will affect the time needed to dissolve the ibuprofen. Hypothesis If the pH of a liquid is…

percentage amounts of ethanol in them; Listerine, Terra Fresca Wine and the last is a mixture of ethanol and water that was made by me. The three different methods compared are the redox titration method which involves the oxidation of ethanol to ethanoic acid and then titrating the residue with sodium thiosulfate, which would then be used to calculate the number of moles of ethanol present in the original sample. The method of distillation involves heating the samples to the boiling point of…

5 : Uses of lecithin. Use Concentration (%) Aerosol inhalation 0.1 IM injection 0.3–2.3 Oral suspensions 0.25–10.0 8 Description Lecithins vary greatly in their physical form, from viscous semiliquids to powders, depending upon the free fatty acid content. They may also vary in color from brown to light yellow, depending upon whether they are bleached or unbleached or on the degree of purity. When they are exposed to air, rapid oxidation occurs, also resulting in a dark yellow or brown…

1. Abstract In this study, reverse micellar extraction of asparaginase model system was carried out using CTAB/Iso-octane/hexanol/butanol system to optimize the forward and back extraction efficiency. By using Taguchi’s orthogonal array (OA), maximum forward extraction efficiency of 55.0%, 61.0% and 54% was achieved with an aqueous phase pH of 11.0, 150mM CTAB/Iso-octane and 0.1 M NaCl, respectively. Similarly, Taguchi’s orthogonal array (OA) was applied to optimize the pH of stripping phase,…
