pH Scale Teacher Resources

What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

Studying acids and bases can be basic. Over the course of four short videos, an instructor explains the pH scale. Viewers observe a demonstration and watch the instructor solve two quiz questions in detail. 

Eighth graders define the pH scale, acids and bases. They distinguish between acidic and basic solutions using litmus paper. Students review simple chemical formulas. They define the subscript and coefficient in terms of chemical...

The pH scale is actually based on logarithms rather than just simple numbers. The fact-filled video begins with an explanation of the auto-ionization of water. Then it describes the relationship between H+ and OH- in every solution. It...

Seeing red? If it was blue litmus paper, then it is an acid. Viewers learn about the pH scale through a video that shows how liquids may be tested by litmus paper and a universal indicator. 

The pH scale is actually based on logarithms rather than just simple numbers. The fact-filled video begins with an explanation of the auto-ionization of water. Then it describes the relationship between H+ and OH- in every solution. It...

Students list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.

Fourth graders compare the color of cabbage water when acids and bases are mixed in. In this acids and bases lesson plan, 4th graders use cabbage water and mix in acids and bases that the teacher prepares before hand. They observe the...

Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...

Most things naturally strive for balance, and acids and bases are no exception. Neutralization of acids and bases allows scholars to explore the color changes associated with the pH scale. After this exploration, pupils neutralize two...

Why are acids and bases important in our daily lives? Lead the class in answering this question, among others, as they experiment with pH paper and classify where various substances belong on the pH scale. They also taste common acids...

Over a 10-year period, EPA regulations cost businesses less than $30 billion, while businesses saved over $82 billion. Scholars experiment with acids and bases to better understand the pH scale. Then they debate environmental regulation...

Pupils experiment to determine the difference between an acid and a base. They study the concept of adding a buffering agent to make an acid more basic. They study the pH scale.

Students become aware of the environmental problems caused by acid rain and study the pH scale. They determine acidity of local rain water.

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

What makes an acid different from a base? The explanation discusses the formation of an acid or base from hydrogen and hydroxide ions. The instruction ends with an overview of how this relates to the pH scale. 

An informative video provides a definition for an acid, where it falls on the pH scale, and how individuals test for them. It uses many examples with chemical equations.

Bring an informative resource to your unit on acids and bases with a video that explains strong and weak acids, pH scales, acids in solutions, dissociation, and dilution. 

Students examine the pH scale. They research common products and determine their pH level. They create their own pH scale and place their products in the appropriate place.

Eighth graders explain the difference between acids, bases and neutral solutions. In this chemistry instructional activity, 8th graders describe the properties of each. They determine the pH of an unknown solution using the indicator...

Chemguy reveals how you can find the pH of a solution from its hydronium concentration. The video is not engaging but is educational.

This PowerPoint progresses slide-by-slide through all the facts you would want to deliver about acids, alkalis, salts, and the related lab tests. Each slide has one or two facts about a physical or chemical property or behavior. The...
