The Ph Scale

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. 

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...

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 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...

Why is pH important? Scholars learn about the pH scale in two of two acid/base presentations. They identify how ionization of water relates to the pH of acids and bases and look at examples on a pH scale of strong and weak acids and...

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...

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...
