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

Reaction on Reaction Paper The first thing that came to my mind when I have heard about Reaction paper is “What exactly is it?” and before I get an understanding of that‚ I resisted that change. But later‚ when I have studied about it and understood its purpose‚ I have started thinking “Why people avoid change at the first look without an analysis?” The general human tendency is to live in a comfortable zone in which he has lived for quite some time. He draws a circle‚ thinks that circle is his

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve

PUTTING IT TOGETHER: Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double
