A. Title – Acid-Base Extraction with Separatory Funnel B. Introduction – The main objective of the experiment was the extract an acid‚ a base‚ and a neutral compound from a 2:1:1 compound of benzoic acid‚ p-nitroaniline‚ and azobenzene. In theory‚ an extraction technique based on phase distribution should allow two immiscible solvents to separate with a portion of the solute distributed into each. Using a separatory funnel‚ acids were extracted with bases (NaOH)‚ and bases were extracted

Experiment 2: Acid- Base Extraction Separation of an Organic Acid‚ a Base and a Neutral Compound Introduction: The extraction technique is often used in the organic lab to separate organic compounds from mixtures. One type of an extraction technique is the acid-base extraction‚ which is used to separate organic compounds from a mixture based on their acid-base properties.1 There are certain principles that must be taken into account when choosing a solvent system to perform an extraction. The solvents should

isolated from tea leaves. This was done through solid-liquid extraction followed by multiple liquid-liquid extraction. Then crude material obtained was then purified by sublimation. The isolated caffeine was subjected to thin layer chromatography (TLC) together with a standard caffeine. The Rf value obtained for both isolated caffeine and standard caffeine was 0.24. Keywords: solid-liquid extraction‚ multiple liquid-liquid extraction‚ sublimation‚ thin layer chromatography‚ percent caffeine

Berry DNA Extraction Lab I. Problem Statement: Successfully extracting the DNA from strawberries. II. Background info: DNA is the genetic information in organisms that codes for proteins‚ and controls the cells function. The DNA is a double helix molecule that is formed by various nucleotides which include Adenine‚ Thymine‚ Guanine‚ and Cytosine with sugar phosphate. Different organisms can have larger or smaller genes. DNA is also what makes up chromosomes during cell replication. Strawberries

’ is the embryo‚ which is the part of the seed that can grow into a new wheat plant. (1) Aim: To extract DNA from Wheat Germ cells‚ and learning the DNA extraction process. Hypothesis: Each step of the process will help in a certain way to extract DNA‚ until we are finally successful in the end. In the wheat germ extraction‚ the ethanol will be able to separate the DNA‚ and it will float between the less dense ethanol and the denser homogenizing mixture. (2) Materials: 1 gram

The purpose of the DNA extraction lab was not only to inform students on how DNA is present in humans and all organisms‚ but to also educate them on how DNA can be extracted using common household materials. Also‚ the lab was very efficient as it introduced the students to extracting their own DNA found on their cheek cells as well as letting them take an observation on how DNA appears or how it is formed. Additionally‚ students were instructed through a very clear and simple procedure‚ which guided

the Indian Edible Oil Industry India is world’s third largest edible oil economy‚ after China and US. India’s annual consumption is around 10 million tones vis-à-vis China’s 14.5 million tones. However‚ India’s per capita consumption at 10.2 kgs per annum is considerably lower compared to global standards. India is also a leading producer of oilseeds‚ contributing 7-8% of world oilseed production. India is estimated to account for around 6% of the world’s production of edible oils. Though it has the
