It is truly amazing to think about how water has so many unique and amazing properties. But just what is it about water that makes it so versatile, useful, essential, and unique?
Barium is an elusive element with not many industrial uses when compared with other metals such as aluminum. However, from a medical drink to rat poison, it would be inaccurate for one to say it didn't have an interesting array of applications.
A detailed guide on how to make litmus paper using red cabbage to test whether substances are acidic or basic. Bases turn green or blue whilst acids turn it red.
A look at the active ingredients in Clorox wipes and Clorox Clean-up and a description of how they work on a scientific level.
REMPI-TOF stands for Resonance Enhanced Multi-Photon Ionization - Time-of-Flight. It is a highly sensitive spectroscopy method for investigation of electron excitation.
The reactions of matter whether occurring in natural processes or in the laboratories can be interpreted using another language of chemistry – the equation. A chemical reaction transforms one or more substances into a set of different substances. The substances that enter into a chemical reaction are called reactants and the substances formed are the products.
Formic acid is found in the sprayed venom of some ants and the secretions of some stinging nettles. The acid is dangerous at high concentrations but has important uses.
Bleach has potent antimicrobial properties and is also able to remove stains from fabrics. It has many uses, but it's potentially dangerous.
This article aims to answer some tricky chemistry questions I have come across in my experience as a high school teacher: What is an acid? How do fireworks change color? How do glow sticks work?
A fuel is defined as a material that stores potential energy that, when released, can be used as heat energy.
What is fractional distillation? How does it work Why is crude oil both important and useless? What is cracking? What is supply and demand? Why do long hydrocarbons have higher boiling points? Modern living is built on crude oil - this hub explains how crude oil is changed into the things we use everyday, from petrol to plastic!
There are many deadly things in the world that can easily bring our lives to an end. But what are the deadliest? Did you know a Japanese delicacy actually contains the 5th deadliest poison known?

We experience many Boyle's law applications in real life every day. Most people don't know it, but an example of Boyle's law is responsible for every moment we are alive. Go science!
A redox reaction is a reaction that involves both oxidation (the loss of electrons) and reduction (the gain of electrons). In order to identify whether a reaction is redox or not, you can write separate half equations that show how electrons are...
How is form related to function? How does primary structure influence tertiary structure? What is the secondary structure of a protein? What is tertiary for that matter? This hub answers these questions and more.
Because caffeine is a substance used by the young and old in every country and on every continent its effects affect billions. In order to better understand these effects we must examine first where and why caffeine exists. We must observe its impact in nature on animals, plants and the environment that reveal the potential ways in which it can change, even destroy, life. Then, we will look at how it relates specifically to us, at the many pathways it impacts in our bodies once we ingest it, a
In this site I discuss 3 possible avenues to nitric acid preparation. They all involve a nitrate salt and a strong acid.
If all the elements are arranged in the order of their atomic weights, a periodic repetition of properties is obtained. This is expressed by the law of periodicity.— Dmitry Ivanovich Mendeleev
Gas is one of the three forms of matter. Every known substance is either a solid, liquid or a gas. These forms differ in the way they fill space and change shape. A gas, such as air has neither a fixed shape nor a fixed volume and has weight.
