The Ph Scale

Explore the range of pH using an assortment of household liquids. Scholars create their own pH indicators from cabbage and determine the pH of several liquids. To further their exploration, individuals use the same liquids to create...

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...

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. 

Is it better to drink an acid or a base? An informative video explains what pH is and how to calculate it. As part of a larger chemistry playlist, it features both the Arrhenius and Bronsted-Lowry definitions. It also demonstrates...

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. 

What makes one acid stronger than another? Pupils peruse the property of pH through a video from the JFR Science playlist. The narrator explains what is meant by a neutral pH, what that looks like from a chemical standpoint, and how...

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...

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...

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...

The ionization of water is explained, acids and bases are defined. Young chemists learn to perform calculations using the equilibrium constant for water. The PowerPoint concludes with information about acid rain. This is a well-organized...
