The students will analyze the pH of four citrus fruits: lime, lemon, orange, and a grapefruit, and then they will analyze the pH of four different types of stain removers: Shout Advanced, Spray 'n Wash Max, Oxi Clean Laundry, and Clorox...

[Free Registration/Login may be required to access all resource tools.] Students will understand and differentiate among acid-base reactions, precipitation reactions, and oxidation-reduction reactions.

This lesson focuses on acids and alkalis including acidic and alkaline solutions, neutral solutions, indicators and the pH scale, the colors for litmus paper, and a link to a test.

This lesson focuses chemical reactions using acidic and alkaline solutions, the pH scale which measures the acidity or alkalinity of a solution, and how to use a pH meter. A link to an assessment is also provided.

This experiment is for all the kids out there who love boiled cabbage. Even if you don't like cabbage, perhaps you will like this amazing color-changing liquid you can make with cabbage. You'll learn which solutions around your house can...

[Free Registration/Login Required] Determination of the Molarity of an Acid or Base Solution.

Students use conductivity meters to measure various salt and water solutions, as indicated by the number of LEDs (light emitting diodes) that illuminate on the meter. Students create calibration curves using known amounts of table salt...

Students use a simple pH indicator to measure how much CO2 is produced during respiration, at rest and after exercising. They begin by comparing some common household solutions in order to determine the color change of the indicator....

In this "kitchen chemistry" project about acid/base chemistry, you will measure the acidity or alkalinity of a solution using a logarithmic scale called the pH scale. As you learn about the pH scale, you will have the chance to make your...

A lab activity where students will neutralize and acidic solution with a base and a basic solution with an acid by using their knowledge of a red cabbage indicator. This site includes teacher and student instruction for the lab activity...

Perform a titration using an indicator to determine the concentration of an HCl solution.

Using the Virtual Laboratory, design an experiment to quickly determine which of the two reagents, HCl or NaOH, is 10 times more concentrated than the other.

NASA keeps its eyes on the Earth in this dynamic site that stays with news about climate change. Includes facts, articles, interactive features, visualizations such as the Climate Time Machine, videos, and lots more.

This lesson plan will allow students to perform pH tests that determine if various solutions are acids or bases (cognitive). Students will test common household solutions such as water, vinegar, milk, and orange juice use pH indicator...

At this site learn about Henry's law through this hands-on experiment. Lab instructions are complete including step-by-step pictures an worksheet.

There are many different types of vinegar that you can buy to use around the kitchen for cooking and pickling. The chemical compound that gives vinegar its tart taste and pungent smell is acetic acid. In this experiment you will work to...
