In this video, we will discuss the 1) results & 2) theory underlying the nitrate reduction test (nitrate broth).<b<br/>r/>

Results are first, and theory (somewhat compli<br/>cated) begins at 7:55.

Learn the basics about solubility rules for insoluble salts, as part of the overall acids, bases and alkali topic.

The video is a chemistry lesson on making insoluble salts. The teacher explains the concept of state symbols and how they indicate if a salt is soluble or insoluble. The teacher also covers solubility rules and how they predict if a salt...

We gotta know how to name all the molecules, and oxyacids are a type of molecule, so let's learn how to name them!

Preserving the environment and developing agricultural products that do not harm unintended targets are top priorities for many scientists and farmers, as well as environmentalists. It's a new era of crop management known as precision...

The Henry reaction is sometimes called a nitroaldol reaction, because it involves the addition of a nitronate salt to a carbonyl compound. This is a great setup for a Nef reaction, which was learned in the previous tutorial. Let's look...

The Nef reaction is a good way to convert nitronates into carbonyl compounds. This is a technique that can be incorporated into a strategy called "Umpolung", which refers to a reversal of polarity, such that upon converting from the...

USDA's Natural Resources Conservation Service in Delaware and its partners are helping farmers take care of their soil and the environment. Jacob Urian of the Kent Conservation District demonstrates how to conduct a Pre-Side Dressing...

Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is...

This live-action video program is about the term nitrogen cycle. The program is designed to reinforce and support a student's comprehension and retention of the term nitrogen cycle through use of video footage, photographs, diagrams and...

Most transition metal cations can do something interesting in solution, they can interact with specific ligands to form complex ions. These coordinate covalent bonds are new territory, so let's get a mini introduction to inorganic...

This lesson will uncover the rules for writing the names and chemical formulae of polyatomic ions and ionic compounds.<br/>
Definitions included: monoatomic ion, polyatomic ion

Baltimore, Maryland is a major city situated on the Chesapeake Bay- a sprawling 64,000 square mile watershed. Currently, the Chesapeake is facing an environmental crisis due to pollutants. Scientist Claire Welty of the University of...

Chemicals interacting with each other are one of the most fascinating topics in chemistry. Fireworks, burning flares, and rusting all illustrate chemical reactions. The different types of reactions are described, as well as the process...

The man accused of selling poison to people who later died has been charged with second-degree murder in connection with 14 deaths in Ontario. Kenneth Law had already been charged with 14 counts of counselling or aiding suicide and is...
