STEM Earth Science lesson plan in which learners learn about measuring and determining the PH of a substance and the impact of acid rain on the environment due to changes of PH.

This simulation uses solutions of weak acids and examines the response of this equilibrium system to the addition of the corresponding conjugate base.

Learn what makes a substance an acid or a base. Learn how salts are formed.

See the changes that occur on a molecular level when acids and bases react. Colorful animations show how the particles interact with each other.

Use the Virtual Laboratory to standardize an unknown NaOH solution (approximately 0.2M) to four significant figures via titration with 25.00 mL of a KHP standard solution.

A twenty-question true-or-false quiz about acids and bases.

[Free Registration/Login may be required to access all resource tools.] Introduction to acids, bases, and pH.

An explanation of historical ideas that lead to the current day concepts of acids and bases. The Concept of pH is briefly introduced.

An introduction, aimed at upper elementary- and middle-school learners, to acid rain. [Click back to home to access the site in Spanish.]

A virtual lab where students determine the concentration of acetic acid in vinegar using a 0.110 M NaOH standard solution and an acid-base indicator, phenolphthalein.

On this site from Chemguide, the titration curves for various acid-base combinations (weak acid/strong base, strong acid/strong base, etc.) are talked about with examples of each given.

This lesson will explain what an acid is, what the pH of an acid is, and give an overview of the general properties of acids. It is 2 of 4 in the series titled "What is an acid?"

Get a brief overview of acids, bases and pH. Explore the pH of a number of different household substances using an extract of red cabbage.

This Shodor Education Foundation page has a nice look at the major theories of acids and bases in less than one page. There are very simple defintions.

This website has a table which gives the typical titration curves for different combinations of acids and bases (i.e., strong/weak, strong/strong, weak/weak, etc.) Also contains an in-depth example problem in which a titration curve is...
