Isopropyl alcohol is a colorless, flammable liquid with a wide variety of uses. It has a wide range of uses in the home and is used in labs, in medicine, and in many manufacturing industries. It is also commonly used as a cleaning fluid. This alcohol does have some toxic properties, so people should be careful when they use it. This experiment involved a mouse on the computer, and the alcohol. The mouse was very dirty, but we wanted to see how dirty it really was. If the isopropyl alcohol really worked, then most of the bacteria would be removed from the mouse. The materials I used for this experiment were a Isopropyl alcohol wipe, swab, petri dish, and a gel-like substance in the petri-dish. First, I divided the gel in the petri dish in…

According to the average density and the boiling point of the experiment, the probable identify liquid of M4C is Propanol (Isopropyl alcohol), with the density value is (0.788 g/mL) and boiling point is (82.67 *C) compare with the literature value of density (0.785 g/mL) and the boiling point (82.4 *C), which Propanol (Isopropyl alcohol) should be the liquid of M4C. The Propanol (Isopropyl alcohol) has no color. The key of identify the unknown is the boiling point and the density, because if…

Question How does distilled water, hydrogen peroxide (H2O2, stabilized, at 3% concentration as a dilute solution), and rubbing alcohol (70% isopropyl alcohol) affect leaves detached from their trees? Hypothesis If I submerge leaves in distilled water, then the leaves will become wet and softer (relative to their original state), because that is what happens to detached leaves after it rains. If I submerge leaves in hydrogen peroxide, then the leaves will become whitened and the distinct…

1:4:4 mixture of water, isopropyl alcohol, and ethyl acetate as the mobile phase. Progression was confirmed by farther travel of the product’s spot vs. the reference sample’s (1-pyrenehexanoic acid dissolve over ethyl acetate). The sample was then extracted with dichloromethane as the organic layer and water. The bottom layer (dichloromethane and sample) following extraction was run through the rotary evaporator to eliminate the solvent, leaving a yellowish solid in the flask. The first amide…

and Investment Company. Caffeine is 1,3,7-trimethyl-3,7-dihydro-1H-purine-2,6-dione. It is white or almost white, crystalline powder or silky crystals. It is sparingly soluble in water, freely soluble in boiling water and slightly soluble in ethanol. It is used as central nervous system stimulant (British Pharmacopoeia 2009). • Methyl paraben was generously donated by Arab Pharmaceutical Manufacturing Company.
