Chemistry Kits

The quantitative stoichiometric relationships governing mass and amount will be studied using the combustion reaction of magnesium metal. Magnesium is reacted with oxygen from the air in a crucible, and the mass before and after the oxidation is

Students will determine the volume of one mole of gas. This is accomplished by generating a known mass of oxygen gas, measuring its temperature, volume and pressure, and then using the data to calculate the molar volume at STP.

A volatile liquid is placed in a test tube and the tube is closed with a stopper with a hole in it. The test tube is placed in a hot water bath.

This kit has been designed to allow the analyst to perform a very simple titration to determine the hardness of their freshwater sample. The titration uses an easily identifiable color transition to indicate the end of the analysis.

In this experiment the indicator eriochrome black T (EBT) is used to signal the presence of ions in the water sample. EBT binds with free metal ions in the water to form a pink complex.

This kit has been designed to allow the analyst to perform a very simple titration to determine the alkalinity of their freshwater sample. This kit allows the analyst to determine both the phenolphthalein as well as the total alkalinity.

This kit has been designed to allow the analyst to perform a very simple titration to determine the salinity of their water sample. The titration uses an easily identifiable color transition to indicate the end of the analysis.

Why are cells microscopic? The answer relates to the needs for the cell to effectively move materials in and remove waste. In this activity, students will create simulated cells (agar blocks) of different sizes and examine how effectively a

Students will study the movement of water and nutrients across a cell membrane and observe osmosis in living tissue. They will then investigate the relationship between surface area and volume as it relates to cells and diffusion.

Three indicators are used in conjunction with acids and bases to create a rainbow of colors. In a basic solution, phenolphthalein is red, p-nitrophenol is yellow, and thymolphthalein is blue.

Students determine the equilibrium constant of three unknown acids and compare the data to known values to identify them. Kit Includes: 1 x 10g Benzoic Acid Crystals 1 x 10g Potassium Hydrogen Phthalate 1 x 10g Sodium Bisulfate (Sodium Hydrogen

In this lab you will learn the history of the discovery of DNA and DNA structure. Understand the nature of genetic inheritance and the role of DNA and proteins in genetic expression while using biological detergents, enzymes, and ethanol to isolate
