Isolating the Components of a Three Component Mixture Essay

The purpose of this lab was to determine the limiting reactant in a mixture of to soluble salts and the percent composition of each substance in a salt mixture.

There are various techniques to separate a mixture of compounds from each other. One of the commonly used way to isolate compounds from a mixture of two compounds is called extraction. This method of extracting two compounds from each other relies on the different solubility of the compounds in two different solvents.

Experiment 55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction, solubility, crystallization and vacuum filtration. The experiment was carried out two times, both of which were successful.

There are millions of different organic compounds. Most of them are found in mixtures and in order to achieve a pure form they need to be separated, isolated, and purified. However, there are endless numbers of possible mixtures, which make it impossible to have a pre-designed procedure for every mixture. So chemists often have to make their own procedures. The purpose of this experiment was to prepare the student to the real world by them designing their own procedure which will help them understand the techniques of separation and purification better. The goal was to extract two of the components of the

The objective of this extraction experiment was to achieve a comprehensive understanding, as well as master the practice, of the technique of separating various individual components of a compound.

These layers can be separated through the use of a seperatory funnel which drains the bottom layer into a separate container. This method uses the understanding of partition ratios of solutes to different paired solvents to produce an equilibrium leaning towards one solvent over another, thereby extracting a compound from one liquid to the other (Padias 128-37). For example, consider a mixture containing two solutes, solute A and solute B, and two immiscible solvents, solvent A and solvent B. If solute A dissolves well into solvent A, but not very well into solvent B, and solute B dissolves well into solvent B but not very well into solvent A, there would be a higher ratio of solute A in solvent A than in solvent B, and a higher ratio of solute B into solvent B than in solvent A. One can then see that, through the use of different solvents, two dissolved solutes can be separated from a mixture. This ratio of a solute concentration to different solvents is defined by K, the distribution constant. Successive filtrations yield’s a higher percentage of products.

The objective of this experiment will be to combine various substances, liquids and metals, and to observe their behavior when they are combined. The types of reactions observed shall determine the nature of these reactions: physical or chemical.

5. Substances in a mixture can be separated depending on the substances involved. You can use a magnet to separate a magnetic substance form a non-magnetic one, filtering, and evaporation. For example, when I put the

This experiment was done in order to understand both fractional distillations and gas chromatography. In addition, this experiment was done to separate and identify two liquids that made up an unknown mixture. Gas chromatography was used to figure out the ratio of these two liquids.

In this experiment, a mixture of unknown #3 was used. That mixture had acid, base, and neutral. We added solvent to the unknown. It is important to know the density of the solvent in order to determine which is the aqueous layer and which is the organic layer. If the solvent that has more density than water, so the organic layer will be the lower layer, while if the solvent has lower density than water, the organic layer will be the upper layer. This will make an error if the determination of the layers was wrong after added the strong acid or the strong base. We added 5% HCl to the mixture in order to separate the base in the aqueous layer and form its salt. Same thing, we add 5% NaOH to the mixture in order to separate the acid and form its salt. In order to recover the base, we add 10% NaOH to the HCl extraction. The result will be salt with a base. Same thing for the acid, in order to recovered it, we added 10% HCl. The reaction will give us salt with an acid. For the neutral, we added sodium sulfate as a drying reagent in order to dry water and separate the neutral part as pure.

The purpose of this separation of a mixture lab is to give students the challenge of figuring out how to separate a provided mixture, and following through with their procedure. The mixture is composed of salt, sand, poppy seeds, and iron filings, and all of these components should be separated and dried as well as possible by the end of the lab.

The purpose of this experiment is to familiarize oneself with the general procedures determining a partition coefficient at the microscale level and learn in weighing milligram quantities of materials on an electronic balance, the use of automatic pipets, the use of transfer pipet, and the use of a vortex mixer. Also, to familiarize oneself with extraction

1. In the space below, list in order the techniques and criteria you used to separate this substance completely from the other fractions.

The purpose of this experiment was to separate a two component mixture using fractional distillation. Distillation is a process of vaporization than condensation of a substance, used primarily to separate substances from a mixture when there are different boiling points. Fractional distillation is when the mixture has multiple substances with similar boiling points, and a fractional column is used to create multiple vaporization/condensation cycles. Fractional distillation is important when two or more substances need to be separated, but they have similar boiling points.

Quantitative analysis is the determination of an amount present in a variety of settings. On the other hand, qualitative analysis is the determination of non-numerical information about a reaction, such as observing that a reaction results in a color change. There are chemical changes that separate cations and physical separations, such as decanting, where liquid is poured from a solid-liquid mixture, leaving the solid behind. Centrifuging is another separation technique, where a solid is separated from a liquid by whirling the mixture at high speed. A mixture of metal ions in a solution can be separated by a reaction of precipitation and in this experiment, the metal cations of aluminum, nickel, and iron ions will be separated from a solution
