3 Component Mixtures Lab Report

Improved Essays
This paper describes the process by which a three-component mixture was separated and identified. The mixture was separated with the aid of a separatory funnel and various solvents acids and bases. The compound was found to be comprised of meta-nitroaniline, naphthalene, and benzoic acid / 2-napthol. All three of them are organic compounds with melting points in the order they were listed 111-114, 79-82 and 121-122/121-123 °C. the percent yield of each component was also calculated at the end based on the initial assumption that the mixture was evenly comprised of all three components.

The unknown three-component mixture was an odorless pale powdery solid. Ether more specifically Diethyl ether commonly referred to as “ether” was an ideal solvent for the unknown component mixture. Its low solubility in water combined with ability to dissolve a plethora of organic compounds and low density make it ideal. Once the mixture was dissolved it was time to separate out the three-components. To separate the base out an acid was used more specifically hydrochloric acid. The acid reacted with basic elements of the mixture and allowed for the simple extraction of the unknown basic compound. The same idea was then again applied when extracting the acid, a bas was used more specifically sodium hydroxide. The acid reacted with this base and separated off allowing us to drain in

What was left in the funnel was assumed to be the neutral component of the mixture. The process for isolating it was simple enough anhydrous magnesium sulfate was available. Magnesium sulfate being an excellent desiccant especially when

    Elizabeth Lee James Poland CHEM 104A 21 September 2014 Discussion and Conclusion of Experiment #4: States of Matter Sleuth Discussion The results of this experiment enabled the experimenter to determine the identity of an unknown salt (#3) using ion-exchange chromatography by analyzing the inorganic salts of the unknown salt, which can be examined by acid-base titration using ion-exchange resin. The stationary phase is made up of acid groups which will attach to the resin, which is then rinsed down the column with water. The mobile phase contains the inorganic salt dissolved in a solvent, which is then added to the column. As it goes down the column, an exchange of H+ ions and cations occur. The solution collected at the bottom of the column contains the acid form of the inorganic salt.…

    Goals The goal of the lab was to investigate the properties and structure of an unidentified compound that was discovered in a local landfill. The group was called in to help determine the chemical and physical properties of the compound so we can let the people of the town know so it can be taken care of properly with or without further precautions to be taken. Another goal of this project was to devise the synthesis of the unknown compound. Experimental Design In order to determine the correct identity of our unknown compound, we first started with a couple preliminary tests, which include physical state and smell.…

    For this experiment, a group was employed by the Environmental Protection Agency as analytical chemists. Their goal was to identify an unknown compound that has been discovered in a landfill in their hometown. Once they identified the compound, they would then have to determine both the chemical and physical properties of the compound in order to inform the townspeople of any potential dangers. During the first week of lab, the group was given a small bottle containing an unknown white crystal-like substance.…

    In this lab we wanted to identify what the four mystery liquids were using density and their characteristic properties. We were initially given four liquids that were labelled numbers 1- 4, some graduated cylinders, and a scale, but we also knew that the 4 liquids were ethanol, vegetable oil, water, and cyclohexane. Using the mass that we found when we measured the liquid and using only 10 mL of the liquids we were able to calculate the density and easily identify the liquids and see if they matched the guesses we had made initially. Our results do confirm our hypothesis that you could identify liquids if you have their densities.…

    Purpose The purpose of this lab was to separate unknown compound 204, composed of an amine, a carboxylic acid, and a neutral component, into each of its three respective states. The unknown compound was separated using microscale separation of acidic, basic, and neutral components by liquid/liquid extraction. Liquid/liquid extraction is a very common method often used in work-ups and allows for isolation of neutral components using acid/base chemistry; this method is extremely helpful in separating reactants and products of a synthesis. The components were purified and dried by evaporation and vacuum filtration.…

    In this lab, we carried out a variety of reactions using different chemicals and metals. A chemical reaction is when the chemical state of the substance you are testing rearranges its ionic and molecular structure. One of the reactions we experienced was single replacement, this consists of one ion switching places with another ion to form a new compound. Another reaction we saw was double replacement. In this reaction, two compounds ions are switched to form two new compounds.…

    After starting with 30 mL of an unknown mixture of two solvents, fractional distillation and gas chromatography were used to identify the unknowns as acetone and toluene in a 1 to 2.04 ratio of acetone to toluene. Fractional distillation was first used to separate the unknown mixture into its components based on boiling point. Distillation refers to the method of separating components of a mixture through heating and cooling. Simple distillation, which is especially useful in the separation of less-volatile substances from volatile substances, such as sugar from water, can be used to separate a liquid-liquid mixture if the boiling points of the component liquids differ by more than 40-50°C. A plot of temperature versus volume for a simple…

    Discussion For the first part of the experiment, a solubility test was conducted on all compounds. Because they were all ionic, every known compound naturally dissolved in water, and conducted electricity. As the next determining factor in the process to identify the unknown substance, the compounds were tested in acetone. As seen in table 2, only one compound, Ca(NO3)2 was found to be soluble in this solvent.…
