Chloroform‚ Acetone and Methanol) for sequential extraction. First of all plant materials were soaked in Hexane for 2-3 days with regular stirring. The mixture was then filtered by using Whatman No. 4 filter paper in to a glass beaker. 300ml of other solvent‚ Chloroform‚ was then added in the residue for 2-3 days. Similarly the mixture was filtered by using whatman No. 4 filter paper. After chloroform‚ Acetone and Methanol were added in residue for sequential extraction. Solvents; Hexane‚ Chloroform

signals the breakdown of fats to provide energy in a process called gluconeogenesis. This breakdown of fats produces ketones such as acetone‚ these molecules are acidic. A build-up of acetone and acetoacetate in Roberta’s blood lowers the pH of her blood. This is known as ketoacidosis. She will begin to rapidly breathe in order to compensate for the high levels of acetone and low pH of her blood. 2. She feels very thirsty despite drinking lots of water. This is a common symptom of diabetes‚ another

A Study of Azeotrope and Acetone/Chloroform Liquid-Vapor Phase Diagram Abstract: Liquid-vapor phase of acetone/chloroform was studied through distilling a series of mixtures with different mole fraction. When the mixtures were boiling‚ their vapor was condensed through a water column and collected in a receiving container. Refractive index was collected for starting mixture‚ distillate and residue for each sample. A boiling temperature versus acetone’s mole fraction was constructed to show the

polish could possibly affect how long it takes to fully remove the nail polish. We then developed an experiment to find out which nail polish brands are removed in the shortest amount of time. We also did a side experiment testing whether acetone or non-acetone nail polish remover removes nail polish the fastest. In the first experiment that we did‚ we got three different brands of red nail polish‚ all displayed at different prices. We hypothesized that if the nail polish brand is more expensive

Water Soluble and Acetone Soluble Inks through Chromatography Abstract: Chromatography is a term used to define a set of laboratory techniques for the separation of mixtures. Through Chromatography we analyzed complex mixtures. In our recent lab we analyzed complex mixtures. The purpose of this lab was to find whether the water soluble or acetone soluble liquid traveled farther. In our recent lab we measured the distance traveled by the different colored water and acetone soluble inks. W put
