Acid-Base Extraction Techniques 5 A commonly used method of separating a mixture of organic compounds is known as liquid-liquid extraction. Most reactions of organic compounds require extraction at some stage of product purification. In this experiment you will use extraction techniques to separate a mixture of an organic acid‚ a base‚ and a neutral compound. Organic acids and bases can be separated from each other and from neutral compounds by extraction using aqueous solutions of different pH values

O’Brien’s Honors Science class we conducted two experiments the Mixed Substances Lab and the Investigating Mixtures Lab. The objective of the Investigating Mixtures Lab was “To observe that not all liquids behave the same way when mixed with other liquids”. Before we started the lab we we each created a hypothesis mine was “If the water and vegetable oil are mixed and the two combine and make a mixture‚ then the vegetable oil will float and the water will sink”. This is the important information which

Sarin Gas Sarin Gas is one the most deadly and toxic gases that has no color and no scent. The formula for this chemical is C4H10FO2P or a more complicated formula or CH3P(=O)(F)(OCH(CH3)2) . This destructive weapon was innovated as a herbicide during the 193040s which is labeled as a nerve agent. Sarin is capable of causing the fatality of someone or the suffocating of a person by just inhaling a low concentration of Sarin gas. Sarin is considered a chiral molecule since it contains four chemical
