A natural deposit containing a mineral of an element to be extracted.
- 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...
- 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...
- 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...
- 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?
- 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...
A salt containing an ionizable hydrogen atom. Acidic salt does not necessarily produce acidic solutions.
The ability of one liquid to mix with (dissolve in) another liquid.
A reaction in which an atom or a group of atoms is replaced by another atom or group of atoms.
A solution that has been titrated against a primary standard. A standard solution is a secondary standard.
The rates of effusion of gases are inversely proportional to the square roots of their molecular weights or densities.
Corrects standard electrode potentials for nonstandard conditions.
Protection of a metal (making ir a cathode) against corrosion by attaching it to a sacrifical anode of a more easily oxidized metal.
Effect by which all acids stronger than the acid that is characteristic of the solvent react with solvent to produce that acid, similar statement applies to bases. The strongest acid (base) that can exist in a given solvent is the acid (base) characteristic of the solvent.
Particles comprising the nucleus, protons and neutrons.
The temperature at which liquid and solid coexist in equilibrium, also the freezing point.
Eluant or eluent
The solvent used in the process of elution, as in liquid chromatography.
Refers to crystals having the same atomic arrangement.
The reaction of a substance with water or its ions.
A reaction that, once initiated, sustains itself and expands. This is a reaction in which reactive species, such as radicals, are produced in more than one step. These reactive species, radicals, propagate the chain reaction.
Alkaline Earth Metals
Group IIA metals
Covalent bond in which there is an unsymmetrical distribution of electron density.
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.
Method by which elemental sulfur is mined or extracted. Sulfur is melted with superheated water (at 170°C under high pressure) and forced to the surface of the earth as a slurry.
A substance that speeds up a chemical reaction without being consumed itself in the reaction.
A substance that alters (usually increases) the rate at which a reaction occurs.
A compound consisting of two elements, may be ionic or covalent.
