Mixtures When two or more kinds of matter are put together a mixture is formed. The process of being mixed does not change the components of a mixture and they retain their individual properties. Mixtures are combinations of substances that are not combined chemically. The amounts of substances in a mixture can vary. Students should understand that
mixtures. Very few materials we encounter are pure. Any material made up of two or more substances that are not chemically combined is a mixture. The isolation of pure components of a mixture requires the separation of one component from another. Chemists have developed techniques for doing this. These methods take advantage of the
See Exhibit 3-A at the end of this section for an example report. Text should be no more than two (2) pages in length (equivalent single-spaced typed). Double-spaced limit is 4 pages. This is going to be hard to do, since there are many components that are going to compete for space. Keep your report short, yet informative. What is the flow of separation of components of a mixture? mixture: SiO2 + NaCl + NH4Cl => sublimate NH4Cl => mix water to residue of SiO2 + NaCl => (WATER + salt + SiO2) => FLITER => Salt-water solution, wet SiO2 => HEAT ( salt-water solution, wet SiO2) => Salt, dry SiO2 = NaCl, SiO2; NH4Cl
If we are interested in separating our mixture into components, we are left with the task of deciding how much material to collect in each receiver and how many receivers to use. Obviously this will depend on the quality of separation we are interested in achieving. Generally, the more receivers we use, the less material we will have in each.
When will simple distillation do a reasonable job of separating a mixture? 1. When the difference in boiling points is over 100C 2. When the there is a fairly small amount of impurity, say less than 10 %. 3. When one of the components will not distil because of a lack of volatility (i.e. sugar dissolved in water).

When separating the solution chemically, the separation is possible because of differences in the way that each component of the mixture reacted with a given chemical. For example, when the SiO2 and CaCO3 mixture reacted to the 3M HCl the CaCo3 began to bubble while the SiO2 sunk to the bottom of the mixture.

Students receive a sample of the mixture, mass it, and then use a magnet wrapped in clear plastic wrap to take out the iron filings. They mass the iron filings then toss them. Many separation methods are based on chromatography, that is, separation of the components of a mixture by differences in the way they become distributed (or partitioned) between two different phases. To illustrate with an extreme example, suppose we have a mixture of gaseous methane and ammonia and contact this mixture with water.

A binary mixture is a mixture containing only two components. We can use a variety of methods, either physical or chemical, to separate the components of such a mixture. Physical separation methods are based on differences between the physical properties of the components, such as solubility or boiling point.
