Chemistry Kits

Demonstrate polymer chemistry. Newsprint is dissolved in a solution of ammonium hydroxide and cupric sulfate.

Show how the first synthetic rubber was made in United States by a reaction of sodium polysulfide with ethylene chloride. This produces a simple condensation polymer consisting of repeating units of ethane and polysulfide.

This experiment will help students understand the importance of proteins, carbohydrates, and lipids in living organisms. They will learn to identify a positive test result for proteins using biuret reagent and examine the reaction between Benedict’s

You will be able to demonstrate the principles of a redox reaction. Paint the potassium thiocyanate solution and potassium ferrocyanide solution onto a filter paper.

A few colored crystals are added to a clear solution in a glass jar or beaker. Within a few minutes large plant like structures extend from the crystals.

Employ Hess’s Law of enthalpy based on the observed data for two reactions. Students can measure the temperatures of the reaction in a calorimeter and analyze the data calculating the enthalpy of each reaction.

The way in which light is absorbed or reflected by a crystalline material is determined by the structure of the crystal. This crystal structure can be changed by the application of heat.

Commercial food colors may contain more than meets the eye. Students will perform thin layer chromatography, a highly effective separation procedure, on four different food colors to determine if there may be more in each color than visual

Chromatography is an analytical tool used to separate similar compounds. Thin-layer chromatography utilizes a sheet coated with silica gel.

TLC is a technique of separation chemistry, which provides a simple, rapid method of separating small amounts of compounds. A mixture of three dyes is prepared and then separated on a thin layer of the absorbent silica gel with the appropriate

In this lab a thionin-iron solution is prepared. Exposing the solution to light energy causes the colored thionin to be reduced by iron (II) ions, resulting in a clear solution.
