Series: Shedding Light on Acids and Bases


Acids and Carbonates

Acids and Carbonates

In this episode, we describe what carbonates are and explain how they react with acids. If it wasn't for carbonates, our own stomach acid would kill us, acid rain would have destroyed our forests, and—worst of all—our pancakes wouldn't be as...Show More
Acids in Industry

Acids in Industry

In Acids in Industry, we look at what acids are, how they're made, and how they're used in steel making and agriculture. We also take a quick trip back to the 1770s to look at how acids were used by Captain James Cook to save his crew from the...Show More
Advanced Acid-Base Chemistry

Advanced Acid-Base Chemistry

In this episode, we take a deeper look at pH and explain how the numbers on the pH scale are actually related to the number of H⁺ or OH⁻ ions present in an acid or a base. We then descend even deeper down—to the atomic level—to explain...Show More
Neutralisation

Neutralisation

In the third episode, Neutralisation, we explain what bases are and then take a look at what happens when acids and bases chemically react. We also take a look at acid-base indicators, which are chemicals that change colour depending on whether...Show More
The pH Scale

The pH Scale

In the fourth episode of this series, we take an in-depth look at H⁺ and OH⁻ ions and we explain how the pH scale is used to express how strongly acidic or how strongly basic a particular environment is. We examine how the pH of natural...Show More
