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...
- Chemical Safety
People use chemicals every day for a wide array of purposes, which can include work and house hold duties. Many of us fail to realize that we are actually handling potentially deadly chemicals when we simply clean the bathroom or wash the car. This brings to mind the reason why chemical safety is...

Diamonds are still a girl's best friend, right? We love the shiny gems. They are the most popular rocks sold today. But what exactly are they, anyway? Where do they come from? What else are they used for?
- What are Compound Microscopes?
Most of the microscopes used today are compound. A compound microscope features two or more lenses. A hollow cylinder called the tube connects the two lenses. The top lens, the one people look through, is called the eyepiece. The bottom lens is known as the objective lens. Below the two lenses is...

Formula
Combination of symbols that indicates the chemical composition of a substance.
Ore
A natural deposit containing a mineral of an element to be extracted.
Bond Order
Half the numbers of electrons in bonding orbitals minus half the number of electrons in antibonding orbitals. Bond order gives an indication to the stability of a bond. Also defined as the difference between the number of bonding electrons and antibonding electrons divided by two.
Solution
Homogeneous mixture of two or more substances.
Hydrate Isomers
Isomers of crystalline complexes that differ in whether water is present inside or outside the coordination sphere.
Effective Nuclear Charge
The nuclear charge experienced by the outermost electrons of an atom, the actual nuclear charge minus the effects of shielding due to inner-shell electrons.
Example: Set of dx2-y2 and dz2 orbitals, those d orbitals within a set with lobes directed along the x-, y-, and z-axes.
Activity of a component of ideal mixture
A dimensionless quantity whose magnitude is: equal to molar concentration in an ideal solution, equal to partial pressure in an ideal gas mixture, and defined as 1 for pure solids or liquids.
Phase Diagram
Diagram that shows equilibrium temperature-pressure relationships for different phases of a substance.
Ionization
In aqueous solution, the process in which a molecular compound reacts with water and forms ions.
Polar Bond
Covalent bond in which there is an unsymmetrical distribution of electron density.
