A soap-like emulsifer that contains a sulfate, SO3 or a phosphate group instead of a carboxylate group.
- 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...
Elements 58 to 71 (after lanthanum).
The lowest energy state or most stable state of an atom, molecule or ion.
A substance that does not conduct electricity at low temperatures but does so at higher temperatures.
Alkaline Earth Metals
Group IIA metals
A binary compound in which H is bonded to one or more of the more electronegative nonmetals.
A piece of volumetric glassware, usually graduated in 0.1-mL intervals, that is used to deliver solutions to be used in titrations in a quantitative (dropwise) manner.
Metal with low ionization energy that loses electrons readily to form cations.
Differential Thermal Analysis (DTA)
A technique for observing the temperature, direction, and magnitude of thermally induced transitions in a material by heating/cooling a sample and comparing its temperature with that of an inert reference material under similar conditions.
The range of concentrations over which a flammable vapour mixed with proper ratios of air will ignite or explode if a source of ignitions is provided.
Equilibrium constant for the ionization of a weak electrolyte.
The process by which solvent molecules surround and interact with solute ions or molecules.
The buildup of a product of oxidation or a reduction of an electrode, preventing further reaction.
Liquids that, when cooled, apparently solidify but actually continue to flow very slowly under the influence of gravity e.g glass.
Percent by Mass
100% times the actual yield divided by theoretical yield.
A binary compound of oxygen.
The energy stored in the nucleus of an atom and released through fission, fusion, or radioactivity. In these processes a small amount of mass is converted to energy according to the relationship E = mc2, where E is energy, m is mass, and c is the speed of light.
Weighted average of the masses of the constituent isotopes of an element, The relative masses of atoms of different elements.
Any species that can accept a share in an electron pair.
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.
Different forms of the same element in the same physical state.
