Negative logarithm of the concentration (mol/L) of the H3O+[H+] ion, scale is commonly used over a range 0 to 14.
- 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...
- Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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?
Conduction of electrical current through a metal or along a metallic surface.
A commercial term used to describe ethanol that has been rendered unfit for human consumption because of the addition of harmful ingredients to make it sales tax-expempt.
At constant temperature the volume occupied by a definite mass of a gas is inversely proportional to the applied pressure.
Photochemically produced oxidizing agents capable of causing damage to plants and animals.
Stereoisomers that differ only by being nonsuperimposable mirror images of each other, like right and left hands, also called enantiomers.
Chemical Hygiene Officer (CHO)
A person or employee who is qualified by training or experience to provide technical guidance in the development and implementations of the provisions of a Chemical Hygiene Plan (CHP)
A salt or ester of salicylic acid.
At the same temperature and pressure, equal volumes of all gases contain the same number of molecules.
Equilibrium or Chemical Equilibrium
A state of dynamic balance in which the rates of forward and reverse reactions are equal, the state of a system when neither forward or reverse reaction is thermodynamically favored.
The amount of heat required to raise the temperature of a body (of any mass) one degree Celsius.
Colloidal suspension of a solid dispersed in a liquid, a semirigid solid.
Formula that indicates the actual number of atoms present in a molecule of a molecular substance.
An Acid that can form two or more hydronium ions per molecule, often a least one step of ionization is weak.
A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
Net Ionic Equation
Equation that results from canceling spectator ions and eliminating brackets from a total ionic equation.
The smallest particle of an element.
A device for measuring pressure.
The sum of the numbers of protons and neutrons in an atom, an integer.
Crystal Field Theory
Theory of bonding in transition metal complexes in which ligands and metal ions are treated as point charges, a purely ionic model, ligand point charges represent the crystal (electrical) field perturbing the metal?s d orbitals containing nonbonding electrons.
The study of rates and mechanisms of chemical reactions and of the factors on which they depend.
