A number that indicates how smoothly a gasoline burns.
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
Common Ion Effect
Suppression of ionization of a weak electrolyte by the presence in the same solution of a strong electrolyte containing one of the same ions as the weak electrolyte.
The smallest repeating unit of a substance. The molecule for nonionic substances
Boiling Point Elevation
The increase in the boiling point of a solvent caused by the dissolution of a nonvolatile solute.
A solid characterized by a regular, ordered arrangement of particles.
Number of moles of solute per litre of solution.
Industrial process by which sulfur trioxide and sulfuric acid are produced from sulfur dioxide.
Fine divided solid particles suspended in polluted air.
Nickel-cadmium cell (Nicad battery)
A dry cell in which the anode is Cd, the cathode is NiO2, and the electrolyte is basic.
An instrument for measuring the amount of salt in a solution. Also,"salimeter, salometer."
The properties of the elements are periodic functions of their atomic numbers.
Adhesion of a species onto the surfaces of particles.
Any of a subgroup of rare-earth elements, of which the cerium and terbium metals comprise the other two subgroups.
A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.
Weak repulsion by a magnetic field.
The metal ion and its coordinating ligands but not any uncoordinated counter-ions.
Freezing Point Depression
The decrease in the freezing point of a solvent caused by the presence of a solute.ing Point
Mass Action Expression
For a reversible reaction, aA + bB cC + dD the product of the concentrations of the products (species on the right), each raised to the power that corresponds to its coefficient in the balanced chemical equation, divided by the product of the concentrations of reactants (species on the left), each raised to the power that corresponds to its coefficient in the balanced chemical equation. At equilibrium the mass action expression is equal to K, at other times it is Q.[C]c[D]d [A]a[B]b = Q, or at equilibrium K.
Beginning in the third energy level, aset of five degenerate orbitals per energy level, higher in energy than s and p orbitals of the same energy level.
Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
Surfaces upon which oxidation and reduction half-reactions, occur in electrochemical cells.
