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...

Interesting facts about metals
Metals have been used by people since ancient times. All the time the process of obtaining them was improved, useful alloys of various metals appeared. Let’s look at interesting facts about metals.

The most expensive metal in the world
Do you think the most expensive metal is gold? No! On earth there are more valuable metals. But we need to divide the value of metals that occur in nature, and metals - isotopes, which are obtained in special laboratories. Let’s look at natural metals first.

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...

What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry. As these quality standards become...

What's In Your Beverage? How to Ensure Quality Control with CO2 Analytical Support
Calibration standards, performance audits, and the FDA's never-ending safety, labeling, and inspection requirements are just the tip of the iceberg when it comes to dealing with the increasingly stringent quality control standards of the beverage industry.
As these quality standards become stricter, beverage producers are increasingly called upon to get products to market faster using fewer resources, while simultaneously managing ingredient quality, and ultimately, risk.
Frequency
The number of repeating corresponding points on a wave that pass a given observation point per unit time.
Rate-law Expression
Equation relating the rate of a reaction to the concentrations of the reactants and the specific rate of the constant.
Galvanizing
Placing a thin layer of zinc on a ferrous material to protect the underlying surface from corrosion.
Band
A series of very closely spaced, nearly continuous molecular orbitals that belong to the crystal as a whole.
Mechanism
The sequence of steps by which reactants are converted into products.
Nonbonding Orbital
A molecular orbital derived only from an atomic orbital of one atom, lends neither stability nor instability to a molecule or ion when populated with electrons.
Standard Electrodes
Half-cells in which the oxidized and reduced forms of a species are present at unit activity, 1.0M solutions of dissolved ions, 1.0atm partial pressure of gases, and pure solids and liquids.
