By figuring out how to change the speed a reaction takes place as well as what gets created in the process, you can get a better handle at creating the things you want. We’re going to learn why fish don’t drown, create glowing slime, turn water into ink you can really write with, make a solution that appears by breathing on it, how to create rubber-like bouncy balls out of clear liquid, shake up a rainbow of colors, learn how to get a lemon to light up a light bulb, and discover what fire really is made of.
Why study chemistry? Baking is chemistry. Cars use chemistry to zip down the street. Your body converts food into energy using chemistry. Everything you see, touch, taste, and smell is a chemical.
Studying chemistry is like peeking under the hood of a racecar – you know you put gas in and it goes, but that’s all you can tell from the outside. Chemistry gets you into the inner workings on the molecular level. Are you ready? This video will get you started on the right foot for your study into chemical kinetics:
It all comes down to controlling the reaction and figuring out what you want to get out of the process. Are you ready? You can get started by watching this video, and afterward either read more about it or start your experiments!
- Different indicators are used for specific ranges of acids and bases. Phenolphthalein changes from clear to pink when added to a base.
- Splitting the water molecule into parts (hydrogen and oxygen) requires power (electrolysis) to break the bonds.
- Thin layers of metal can be moved from one object to another using the electroplating technique.
- Chemists want to control the speed of a reaction as well as what gets generated from the process (the products of the reaction).
- Several factors affect the speed of a chemical reaction, including catalysts, surface area, temperature, and concentration.
- Polymers are long chains of slippery molecules. Coagulation happens when you cross-linking the chains into a fishnet-looking design.
