Eighth graders study the concepts of acids, bases, salts and neutralization. They discuss steam adoption program, acid rain and other ecological implications. They use indicators to obtain pH values of household chemicals and to...

Students wxplore acids and indicators by watching a demostration in which "magic" ink appears. They duplicate the demonstration by writing magic messages using phenolphthalein solution and painting the message with vinegar to show it.

Students explore acids, bases, and indicators. They observe the various colors of an acid-base indicator solution and the neutralization of an acidic solution by an antacid.

Students explore acids and bases and the process of neutralization.T hey practice volume measurements and observe the neutralization of an acid directly through bubble formation and indirectly through indicator color changes.

Students explore acids and bases. They experience the sour taste of acids and the bitter taste of bases by tasting substances such as chocolate, lemon juice, and baking soda. in addition, they complete a worksheet for individual assessment.

Middle schoolers observe chemical reactions using post-1982 pennies. They observe the reaction of an acid with zinc but not copper under the same conditions over a two week period.

Students estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.

Students use purple cabbage indicator to test five know substances for acidic/alkaline balance. They discuss the safety precautions required both inside and outside a lab in handling acids and bases.

Students conduct an experiment called "What's the Solution? Acid, Base or Neutral." to determine the differences between these types of substance.

Learners use a pH indicator to measure the pH of some fruits, common beverages, and borax. Students discover how to differentiate between an object that is an acid or a base.

Students examine how mining and other industry operations can lead to acid runoff.  In this mining lesson students study weathering and complete a lab on it. 

Eighth graders experiment what happens when acids and bases are mixed together. In this acids and bases experimental instructional activity, 8th graders decide which of three solutions of unknown pH will neutralize a fourth solution of...

In this ions worksheet, learners use a charge chart in a textbook to determine the charges of different types of compounds. This worksheet has 24 fill in the blank questions.

Students determine the pH level of water and its effect on aquatic plants and brine shrimp eggs. This is a three part lesson that leads the student through the development of an understanding of water pH. They form a hypothesis and are...

Students collect water samples from around your home and school, check the pH level of each water sample, and record the pH levels in a chart that looks something like this:

As a chemist, you will learn to deal with complex mixtures of many compounds. In this interactive activity, you will learn the basis of separations using acid-base extraction. In the virtual lab you will simulate an actual experiment and...

This site defines pH and provides several relevant examples and calculations.

Did you know that chemistry can be found in your kitchen? Enter this amazing virtual world where your first stop is to the kitchen. Locate the clues and move on to the Lab Journal where you can test each item in two experiments: Cabbage...

This article, which is provided for by the Florida State University Lecture notes on the dissociation of water. An interesting site to check out on the subject.

Vview molecular structures and formulae of four common acids - acetic, nitric, phosphoric, and carbonic. Manipulate each structure to view it in a three-dimensional format.

Learn about the solvent properties of water, pH, pKa and buffering capacity with a series of problems. The correct answers for the multiple choices problems are reinforced with a brief explanation and the incorrect answers are linked to...
