We use electrolysis to break water molecules down into hydrogen and oxygen. This is done using the Hoffman apparatus. Water is added to the apparatus along with some dilute sulfuric acid. When a current is passed through the water,...

In this video, you'll learn:<br/>
- The test for detecting c<br/>hlorine gas
- The test fo<br/>r detecting oxygen gas
- Th<br/>e test for detecting hydrogen gas
- The test for detecting carbon dioxide gas

Ever wondered how to conduct a chemical test for the presence of colourless and odourless gases? Watch this to find out how!

Learn the basics about Testing for hydrogen, oxygen, carbon dioxide and chlorine. Why do we need to test these particular gases? Find out more in this video!

This is a lecture presentation on the electrolysis of aqueous solutions. The presenter explains what an aqueous solution is and what it contains, particularly aqueous solutions of metal salts. The presenter then presents a hypothesis on...

The video discusses the composition of air, specifically the gases nitrogen, oxygen, argon, and carbon dioxide. The presenter explains how these gases react with certain compounds and how they can be made from other substances. The video...

This video discusses the various tests that chemists use to identify different gases like hydrogen, oxygen, carbon dioxide, chlorine, and ammonia. The presenter demonstrates each test using simple equipment like test tubes, splints, and...
