Description
This program familiarizes students with the features of acids and bases, and discusses their physical and chemical properties. The pH scale is introduced with examples of strong and weak acids and bases and the concept of neutral substances is explored. The use of indicators to test the pH of acids and bases is explained, as well as showing the variety of indicators available and their specific uses. Students are shown how to make their own red cabbage...

Fire retardant used to smother fires—also called slurry—is a mixture of water, fertilizer and chemicals. It’s dropped from planes and is usually a bright red color, so air crews can track what they’ve used. But this powerful way to help slow down fires also comes with a big price tag and some environmental concerns.

Description
Salt, that seasoning you put on food, is also one of the most important substances on Earth. It has been so important to humankind that it has caused wars to erupt and civilizations to be born or to crumble. Learn all about its role in human history, the chemistry of salt, ways of obtaining common salt, the purpose of salt in the human body, why we can’t drink sea water, and more! It has far more significance than you ever would have imagined!

Description
Matter is all around us. Everything on earth is made of matter. Learning about the different properties of matter will allow students to understand how environmental and human factors affect the changing world we live in. By viewing the video, students will enhance their knowledge about solids, liquids, and gases. The video presents general information about matter, matter's properties and states, and how matter changes. After viewing the video, students...

From an instantaneous explosion to the slow rusting of iron, the rates at which different chemical reactions proceed can vary tremendously depending temperature and concentration. Chemists want to slow down or speed up reaction rates. One way to do this is to use a catalyst. In this video, we will learn about catalysts and how using them can lead to cheaper, more effective drug production processes.

Solution chemistry provides tools to measure the concentration of components of solutions, like the CO2 levels in ocean water. The majority of chemical reactions happen in solutions. For example, when we breathe, the nitrogen in the air dissolves in our blood. Henry's Law gives us the power to predict, prevent, and treat "the bends," a life-threatening condition that can happen to SCUBA divers when nitrogen in the blood comes out of solution and forms...

The chemistry of solid-state materials characterizes most of the interactions we have with matter on a daily basis. Chemists take advantage of the complexity of solids to engineer new materials, including nanoparticles, polymers, and advanced metal alloys. These new materials have many potential applications in sensors, advanced drug delivery systems, and space exploration.

Description
Very little in the physical world occurs without chemical reactions being involved. This program takes an in-depth look at five common products-soap, polystyrene, aluminum, paint, and car batteries-and explores the chemistry behind their manufacture and use. With the help of graphics and footage from inside manufacturing plants, the video reveals just how surface chemistry, redox chemistry, metals, and polymers play a part in everyday life.
