A substance that conducts electricity well in a dilute aqueous solution.
- 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...
- 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...
Compounds containing predominantly ionic bonding.
Standard Molar Enthalphy of Formation
The amount of heat absorbed in the formation of one mole of a substance in a specified state from its elements in their standard states.
A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
Different substances that have the same formula.
Two or more forms of atoms of the same element with different masses, atoms containing the same number of protons but different numbers of neutrons.
Metal with low ionization energy that loses electrons readily to form cations.
An organic ion carrying a negative charge on a carbon atom.
A dry cell in which the electrolyte contains KOH.
Homogeneous mixture of two or more substances.
Hydrated sulfates of the general formula M+M3+(SO4)2.12H2).
A white, needlelike, crystalline, water-soluble solid or syrup, C6H10O8, usually made by the oxidation of cane sugar, glucose, or starch by nitric acid. Also called "Glucaric acid."
The number of repeating corresponding points on a wave that pass a given observation point per unit time.
Any of a subgroup of rare-earth elements, of which the cerium and terbium metals comprise the other two subgroups.
Compound containing both an amino and a carboxylic acid group.The --NH2 group.
A fairly strong dipole-dipole interaction (but still considerably weaker than the covalent or ionic bonds) between molecules containing hydrogen directly bonded to a small, highly electronegative atom, such as N, O, or F.
Refers to the occurrence of an element in an uncombined or free state in nature.
Water containing Fe3+, Ca2+, and Mg2+ ions, which forms precipates with soap.
The rate at which a particular substance will vapourize (evaporate) when compared to the rate of a known substance such as ethyl ether. This term is especially useful for health and fire-hazard considerations.
Number of moles of solute per litre of solution.
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.
