Lab report on separation of mixtures Purpose- The purpose of this lab is to separate or isolate the desired product from large amounts of solvent and by-products. It is also followed by a purification step that removes trace amounts of other substances from the final product. One of the experimental techniques that we used in the lab to separate or purify mixture is fractional crystallization. In the experiment we used fractional crystallization to resolve a mixture of salicylic acid and CUSO₄ .5H₂O

Title: Lab #3 Separation of a Mixture of Solids Purpose: To understand the different separation methods and techniques that depend on the chemical properties of a specific substance. Also to become more comfortable with performing those actions of separation so I have them in the future. For this experiment‚ I will separate a mixture of four distinct substances: sodium chloride‚ benzoic acid‚ silicon dioxide‚ and iron fillings into pure beings. Procedure: Materials: distilled water coffee

3Quantitative Separation of Mixtures This experiment performs the quantitative separation of thecomponents of a mixture. A mixture is the mixing of two or more substancestogether. The proportions of the components in the mixture can be varied.And the resulting mixture can be either homogeneous or heterogeneous‚depending on the properties of components such as solubility.In this experiment‚ you are going to separate a water-solublecomponent from water-insoluble components. The heterogeneous

Alvarenga Lab Partner: Keren Appiahene Mussie Gide 10 September 2016 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

Wang Experiment #4 Recrystallization of Pure Phthalic Acid‚ Benzoic Acid and Napthalene Introduction Recrystallization is a important method in purifying organic compounds which are solid. It is an effective method that is important to be familiar with that is essential in the industrial chemical world. This experiment will allow students to be familiarized with the technique of recrystallization by working with phtalic acid‚ benzoic acid and naphthalene from appropriate organic solvents.

Benzoate from Benzoic Acid October 28‚ 2010 Abstract: This experiment was conducted to synthesize methyl benzoate from benzoic acid and methanol by using the Fischer esterification method. Methanol (12.5ml) and Benzoic acid (4.9 grams) are heated together in the presence of concentrated sulfuric acid (1.5ml) until equilibrium is achieved. A reflux apparatus is set up for 1 hour to carry out the reaction at the boiling point of the solvent (Methanol‚ 2.5ml). Then‚ separation though an extraction

Gorman and Tyler Kui) Lab #1: Separation of a Mixture Mr. Mejia 10/3/14 Separation of a Mixture Lab Report Abstract The purpose of the experiment was to separate an initial heterogeneous mixture composed of 5.00 grams of salt‚ 2.00 grams of sand‚ 50.0 mL of water‚ 15.00 grams of pebbles‚ and 1.00 gram of iron filings‚ and leave as much salt as possible remaining. Using separation techniques including magnetizing‚ evaporation‚ filtration‚ etc. the heterogeneous mixture was thoroughly separated into

Acid-Base Extraction: Separation of an Organic Acid‚ Base and a Neural Compound Introduction/Background Acid base extraction is a widely used commercial method in separating acids‚ bases and neutral compounds. This is concept is based on several physical properties of the compounds‚ such as boiling point‚ melting points and solubility. The different solubility properties of the protonated and non-protonated forms of these compounds depend on the functional groups present‚ such

Experiment 2&3 Recrystallization and Melting Points Determinantion of Benzoic Acid Abstract In experiment 2‚ recrystallization was used to purify the crude benzoic acid extracted from a mixture during experiment 1. Then a percent recovery for this recrystallization process was calculated. In experiment 3‚ the melting point ranges of the crude and purified benzoic acid were both determined by using Melt Temp Apparatus. Introduction Recrystallization is a purification technique for non-volatile
