An instrument that measures the charge-to-mass ratio of charged particles.
- Diamonds Are Forever
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?
- 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...
- 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...
- 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...
- 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...
The pressure of the gas above a solution is proportional to the concentration of the gas in the solution.
Hydrocarbon derivative containing an [OH] group bound to an aromatic raing.
The vapor pressure of a solvent in an ideal solution decreases as its mole fraction decreases.
Crystal Field Stabilization Energy
A measure of the net energy of stabilization gained by a metal ion's nonbonding d electrons as a result of complex formation.
A series of compounds in which each member differs from the next by a specific number and kind of atoms.
Corrects standard electrode potentials for nonstandard conditions.
Isomers of crystalline complexes that differ in whether water is present inside or outside the coordination sphere.
D -Transition elements (metals)
B Group elements except IIB in the periodic table, sometimes called simply transition elements EX. Fe, Ni, Cu, Ti .
For further information see Metals.
A small amount of radioisotope replacing a nonradioactive isotope of the element in a compound whose path (for example, in the body) or whose decomposition products are to be monitored by detection of radioctivity, also called a radioactive label.
Symbol for an atom A/Z E, in which E is the symbol of an element, Z is its atomic number, and A is its mass number.
Potential difference between two electrodes, a measure of the chemical potential for a redox reaction to occur.
The solute-like species in a colloid.
Compound in which an oxygen atom is bonded to two alkyl or two aryl groups, or one alkyl and one aryl group.
Band Theory of Metals
Theory that accounts for the bonding and properties of metallic solids.
Particles comprising the nucleus, protons and neutrons.
Vaporization of a liquid below its boiling point.
A solution that obeys Raoult's Law exactly.
Boiling Point Elevation
The increase in the boiling point of a solvent caused by the dissolution of a nonvolatile solute.
Concentration expressed as number of moles of solute per kilogram of solvent.
Free Energy Change
The indicator of spontaneity of a process at constnt T and P. If delta-G is negative, the process is spontaneous.
