Introduction: The theory behind the extraction of a solution containing benzoic acid‚ cellulose‚ and methyl orange involves many components pertaining to the fundamental ideas of solubility and polarity. Using the concepts of like dissolving like and acid base reactions‚ a solution of organic acid (benzoic acid)‚ a water soluble compound cellulose‚ and an organic soluble compound methyl orange‚ can be separated and benzoic acid can be isolated by a method of extraction. At the fundamental level

methods of procedure that can be used for later experiments. This experiment involves the separation of benzoic acid from a more crude form‚ consisting of benzoic acid‚ methyl orange‚ a common acid/base indicator‚ and cellulose‚ a natural polymer of glucose (Huston‚ and Liu 17-24). The technique that is used to perform this separation is called extraction. Extraction is a systematic process of separating mixtures of compounds‚ taking advantage of the affinity differences of compounds to separate them

Title: Separation of a Mixture of Solids Purpose: Learn and demonstrate how to separate different ingredients from a mixture of solids using different methods based on the properties of each ingredient. Procedure: I weighed mixture and tools‚ and proceeded to begin separating each ingredient. I used a magnet to separate the iron from the mixture. Then I heated the mixture in water to get the non-soluble sand out. Then I filtered out the benzoic acid after cooling it into a crystal form

Use your digital scale to determine the mass of your weighing dish. b. Empty the entire mixture of solids from the plastic bag into the weighing dish and determine the gross mass of the total mixture and weighing dish. Compute the net mass of the mixture: this is equal to the gross mass of the weighing dish with the mixture less the

Separation Techniques If one component of the mixture has magnetic properties‚ you can use a magnet to separate the mixture. Cobalt‚ iron and nickel all have magnetic properties. Note that not all metals are magnetic and magnetism is not a method to separate metals from non-metals. Gold‚ silver and mercury are examples of non-metal substances. Magnetism is however a way to separate magnetic substances from non-magnetic substances is. Magnetism as a separation method is done by taking any magnetic

Separation of Mixtures 9/11/11 * Introduction: A compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Unlike a compound‚ a mixture is a material system made up by two or more different substances which are mixed together but are not combined chemically. There are two kinds of mixtures‚ homogeneous and heterogeneous. Homogeneous mixtures have the same composition and appearance throughout

Crystallization of Benzoic Acid Purpose: The purpose of this experiment is to purify benzoic acid by crystallization. Procedure: 1. 0.5g impure benzoic acid was placed in a 50mL Erlenmeyer flask. 15mL of water was added and the mixture was heated to a boil on a hot plate. 0.5mL of water was added to the flask‚ while swirling the flask. The mixture was boiled until the benzoic acid completely dissolved. The total volume of water used was recorded. The black solid that remain in the dissolved
