Why do copper products change color, and what is the name of the process?
Probably, every person wants to know, why over time the copper turns green and becomes bloomed. This is easy to explain: that film is called patina.

Creating Malachite egg
One of the most interesting and obvious chemical experiments is the experiment on the interaction of copper sulfate and calcium carbonate. The latter is contained in the shell of a simple egg, but copper sulphate should be searched in a chemical reagent store. This experience is simple, but...

Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to...

Varieties of garnet minerals
The most famous type of garnet stone is pyrope (flaming). This is the "oldest of garnets", with a dense red color, similar to the grain of an edible garnet. Pyrope has a variety called rhodolite - a stone of dense pink or pink-purple color, which sometimes has the alexandrite effect and is used in...

Electrolytic Cells
Electrochemical cells in which electrical energy causes nospontaneous redox reactions to occur. An electrochemical cell in which chemical reactions are forced to occur by the application of an outside source of electrical energy.
Harmful Chemicals Found In Food
It's getting close to New Years and many people are starting to think about how to lose those extra pounds they managed to gain over the holidays. There are many sorts of diets and fads that have developed over the years from cutting carbs to cutting protein. Everyone has their own opinion as to which one is healthy or not and which produces the best results. There is one thing that almost every can agree on. That being high sugar and caffeine products like sodas are not good for you, but those are not the only dangers found in food and beverages.
Geometrical Isomers
Compounds with different arrangements of groups on either side of a bond with restricted rotation, such as a double bond or a single bond in a ring, for example cis-trans isomers of certain alkenes. Stereoisomers that are not mirror images of each other, also known as position isomers.
Bronsted-Lowry Base
A proton acceptor
Reaction Quotient
The mass action expression under any set of conditions (not necessarily equlibrium), its magnitude relative to K determines the direction in which the reaction must occur to establish equilibrium.
Optical Isomers
Stereoisomers that differ only by being nonsuperimposable mirror images of each other, like right and left hands, also called enantiomers.
Greenhouse Effect
Trapping of heat at the surface of the earth by carbon dioxide and water vapour in the atmosphere.
Hydrate Isomers
Isomers of crystalline complexes that differ in whether water is present inside or outside the coordination sphere.
Explosive
A chemical or compound that causes a sudden, almost instantaneous release or pressure, gas, heat and light when subjected to sudden shock, pressure, high temperature or applied potential.
Radiation
High energy particles or rays emitted during the nuclear decay processes.
