Chem1 Online Textbook Main Menu. Acid-base chemistry can be extremely confusing, particularly when dealing with weak acids and bases.
This set of lessons presents an updated view of the Brønsted-Lowry theory that makes it easy to understand answers to common questions: What's the fundamental difference between a strong acid and a weak acid? Can acid A neutralize base B? Why are some salts acidic and others alkaline? How do buffers work? What governs the shapes of titration curves? This complete rewrite of the previous 1996 pdf document is now organized into seven lessons covering all aspects of the subject. Chemistry 101 - Introduction and Index of Topics. By Anne Marie Helmenstine, Ph.D.
Updated March 16, 2016. Welcome to the world of Chemistry 101! Chemistry is the study of matter. Like physicists, chemists study the fundamental properties of matter and they also explore the interactions between matter and energy. Chemistry is a science, but it is also used in human communication and interaction, cooking, medicine, engineering, and a host of other disciplines.

The 45 separate video chapters that make up the course may be viewed either individually or as part of a certification sequence. In order to become “Flinn Certified” you must watch all 45 videos in sequence and complete a series of the unit assessments to document the safety training. If you choose to view the videos individually you will have the freedom to skip around and select any video of interest. You will always have the ability to switch between viewing individual video chapters and participating in the certification course in the “My Progress” portion of your “My Account” page. Chapter notes will be available to print on that specific video player page. Home Chemistry: Experiments. We recently tried a new and improved version of the lava lamp project from several years ago.
It worked great! Here's how we did it: Tools and Materials: • Clean recycled soda or water bottle, label removed, 16 oz or larger • Water • Food coloring • Baby oil, at least one 12 oz bottle • Effervescent antacid tablets (such as Alka-Seltzer) • LED push light (or make a light-up base from a recycled jar or can, some extra bright LED bulbs, coin batteries, and tape) • Plastic plate or other protection for table • Cooking (meat) thermometer (optional) Step 1: Prepare the lava lamp bottle. The first step in building your homemade lava lamp is to find a tall, thin, clear bottle. Step 2: Prepare the Bottom Layer of Colored Water. Chem Academy. Quarks and Quirks. DONE!

Battle of the Slime! ChemMatters Magazine. Chemicool. Here’s a look at the remarkable properties of ten of the periodic table’s elements.
The first on our list was hailed as the philosophers’ stone when it was discovered. 1. Phosphorus Phosphorus was the first element ever isolated scientifically. In 1669 Hennig Brand evaporated water from urine, then allowed the residue to fester for a few months. When he distilled the residue, one of the substances that appeared was phosphorus. Some alchemists thought Brand had discovered the philosophers’ stone! The Alchemist by Joseph Wright depicts Hennig Brand’s discovery of phosphorus. 2. Carbon forms more compounds than any other element. Carbon’s ability to bond with other elements makes it the ideal basis for life, such as this excited gull. 3. Gold is the most ductile, or drawable, of all metals.
