Ampholytes are compounds which react with both acids and bases. When zinc chloride is reacted with sodium hydroxide the soluble zincate ion is formed. When zinc hydroxide is reacted with...
Catalysis is a basic principle of chemistry and biochemistry. Some reactions are autocatylic; the product of the reaction actually catalyzes further reactions. The reaction is initiated with acid and produces...
Demonstrate polymer chemistry. Newsprint is dissolved in a solution of ammonium hydroxide and cupric sulfate. The solution is then added to a sulfuric acid solution and dark strands are formed.
The gas laws (Boyle’s, Charles’s and Gay-Lussc’s) are simple mathematical relationships between volume, temperature and pressure. By varying one component you can measure the effect on the other three. Gases...
Through the use of a gas pressure sensor, you will be able to monitor the pressure change in a sealed environment and the pressure change provides an indication of the...

Electromagnetic radiation in the UV range of the spectrum cannot be perceived by the human eye. Using the Neulog™ UVB sensor specifically designed to measure UVB radiation, you will compare...
The photosynthesis/respiration demonstration chamber may be used to monitor oxygen levels, carbon dioxide levels, or both in an enclosed environment. The chamber has been designed to be used with the...
Monitor the voltage generated by a biological fuel cell, using the yeast Saccharomyces cerevisiae. A simple sugar will be used as a food source for the yeast and methylene blue...
