Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.Worksheet: Have students answer the Chromatography Lab Worksheet questions and hand them in for grading (see answers in the Wrap-Up Discussion, below). Review their answers to gauge their comprehension of the material.

Who has heard of chromatography? Chromatography is a way to look at complex mixtures by separating them into their components. The separation of a mixture into its components is a physical process; that is, because the components of the mixture are not chemically combined, they can be separated by physical means. Criminal investigators use this technology to identify substances such as drugs, blood, ink and other fluids.

A super-strong cleaner might remove the stain, but that won’t help if it damages the fabric as it cleans. A good understanding of solutions and mixtures and their components, in addition to reaction, is essential for environmental engineers.

A careful pretreatment and thorough cleaning can often clean out stains that you thought were going to be there forever. Pretreat your stains with liquid detergent before running them through the wash. Use cold water to avoid baking in the dye.Sharpie stains don’t only occur on fabrics and hard surfaces, of course.

Understanding chemical reactions can also help environment engineers remediate contaminants in water. For example, engineers can use chemical oxidants to degrade certain contaminants; in other words, the contaminant reacts with the treatment chemical to produce a product that is benign, or harmless, unlike the contaminant. Some common indicators of reaction include: changes in odor, temperature, or color, production of gas, or precipitation. However, the only way to be absolutely certain of whether a chemical reaction has occurred is to perform a chemical analysis to determine whether a new chemical is present. Sharpie" was originally a name designating a permanent marker launched in 1964 by the Sanford Ink Company (established in 1857). The Sharpie also became the first pen-style permanent marker.
