Perform virtual lab experiments safely. Pour and mix specific amounts of various solutions on screen and observe changes in temperature and pH. Choose glassware and other tools (ie. bunsen burner, scale) to assist with virtual lab...

A collection of video lectures from a general chemistry course taught at the University of California, Berkeley. The course teaches periodic table, chemical bonds, molecular shape, phase changes, chemical reactions, stoichiometry,...

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] This is a game format activity based on the TV game Deal or No Deal. The game is Grade or No Grade. Students answer a series of questions on Chemistry topics of Acids, Bases and Solutions.

Learn about the autoionization of water, the autoionization constant Kw, and the relationship between [H+] and [OH-] in aqueous solutions.

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.

Acids and bases are scaled. These facts are good knowledge to have when classifying solutions as acidic, basic, or neutral.

A picture of the crystal structure of calcium hydroxide. Additional plug-in required.

This page has animated 3-D graphics that illustrate the dissociation of strong and weak electrolytes.

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...

Students see a demonstration of a color change using universal pH indicator and then change the concentrations of an acid and a base using a universal indicator to test the pH of the resulting solutions. Through an animation, they see...

This tutorial presents a review of the definitions for pH and buffer solutions

A collection of video lectures from a general chemistry class for high school students. Lectures cover topics such as equilibrium, thermochemistry, electrochemistry, and acids and bases with forty-four lectures. Lectures vary in length...

Definitions of pH, pOH, and the pH scale. Practice calculating the pH of a strong acid or base solution. Learn the relationship between acid strength and the pH of a solution.

[Free Registration/Login may be required to access all resource tools.] A complete, web-based, multi-media textbook covering a wide variety of Chemistry concepts.

This is a titration and ph math problem exercise; the answers are also provided.

Review examples of macro and micro pH scales of a variety of substances available in a drop down menu. Create a solution to measure.

A video tutorial demonstrating how to calculate the pH of a solution given the hydrogen ion concentration. [3:44]

This lesson will provide an understanding of the chemical and physical nature of water. It is 3 of 4 in the series titled "The Properties of Water."

This lesson will provide an understanding of the chemical and physical nature of water. It is 1 of 4 in the series titled "The Properties of Water."

This activity is a fast and safe microscale experiment which allows students to quickly determine the molarity of three weak acids (vinegar, soda, and citric acid). Since the process involves a monoprotic, diprotic, and a triprotic acid,...

A collection of video lectures from a course that investigates the application of basic chemistry principals to engineering systems. The course draws from industrial practice to give examples of the application in engineering systems. In...

Buffers are solutions that resist a change in pH. In this activity, students will add HCl dropwise to a measured amount of water, monitoring the pH. Students then repeat the process, using a simple buffer prepared by combining baking...
