Chemistry

Examine the properties of acids and bases with this high-quality kit. Students get a complete introduction to acids and bases.• Test acids and bases with litmus paper and phenolphthalein indicator.• Examine how pH is related to the strength of an aci...

Explore acid-base reactions with this in-depth kit. Students learn about pH, acid-base indicators, antacids, neutralization, and titration as they perform six different experiments:• Study a neutralization reaction to make a simple salt.• Use antacid...

Several titrations can be performed during one class period with surprisingly good results. Students determine the percentage of acetic acid in household vinegar by titrating the vinegar with a sodium hydroxide solution of known concentration. The in...

Proper pH is a true vital sign-in the blood, in the lungs, and throughout the body! How do buffers maintain the delicate pH balance needed for life and health? Explore the properties of biological buffers in this two-part kit. In Part 1, students exa...

Watch paper chameleons magically change color with the help of some basic-and acidic-chemistry. Students spot solutions of various household substances on specially treated blotting paper, then estimate the pH of each by the color produced. Creativit...

Investigate the chemistry behind an exciting “popping” toy. A chemical reaction within a sealed bag rapidly produces carbon dioxide gas, expanding until the bag breaks with a loud pop that will grab even your most inattentive student's interest! Stud...

Swimming pools, lakes, our bodies-all require specific pH levels! Your students will gain a clear understanding of pH with this introductory kit. Students will test six indicators and record their colors in acidic and basic environments. Not only wil...

Teach about the important topic of acids and bases using toys! These small toys are sealed Mylar pouches containing a packet of “magic water” and a white solid. Activate the toy by breaking the water pouch and shaking-step back and wait for the pop, ...

Do your students understand why some acids have lower pH values than others, even though their concentrations are the same? Acids vary greatly in their strength-their ability to produce hydrogen ions when dissolved in water. This lab will help you ex...

Students carry out a series of dramatically colorful tests while they learn that:• Indicators can be acidic or basic.• Each indicator has a specific pH range.• Indicators can be combined to create a specific guide.• A color guide created by each stud...

Roses are red, violets are blue-or are they? Red roses, as well as many other flowers and fruits, contain natural indicators that are sensitive to acids and bases. The color of a natural acid-base indicator depends on pH. In this activity, the pH sca...

Buffers provide an essential acid-base balancing mechanism-in consumer products, foods, even living cells! What are buffers made of? How does a buffer work? Can you design a buffer to be effective in a given pH range? Is there such a thing as an idea...
