Liquids that, when cooled, apparently solidify but actually continue to flow very slowly under the influence of gravity e.g glass.
- 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 OH group.
A catalyst that exists in a different phase (solid, liquid or gas) from the reactants, a contact catalyst.
A unit of pressure, the pressure that will support a column of mercury 760 mm high at 0 °C.
For acid-base titrations, organic compounds that exhibit different colors in solutions of different acidities, used to determine the point at which reaction between two solutes is complete.
Any species that can accept a share in an electron pair.
Any state other than the ground state of an atom or molecule.
The mass of one molecule of a nonionic substance in atomic mass units.
A class of enzymes found in bacteria within root nodules in some plants, which catalyze reactions by which N2 molecules from the air are converted to ammonia.
A small amount of radioisotope replacing a nonradioactive isotope of the element in a compound whose path (for example, in the body) or whose decomposition products are to be monitored by detection of radioctivity, also called a radioactive label.
A substance that conducts electricity poorly in a dilute aqueous solution.
The rotation of plane polarized light by one of a pair of optical isomers.
An equilibrium constant for a hydrolysis reaction.
A gas filled tube which discharges electriaclly when ionizing radiation passes through it.
The sum of the molalities of all solute particles in a solution.
Process that occurs in electrolytic cells.
Emission of an electron from the surface of a metal caused by impinging electromagnetic radiation of certain minimum energy, current increases with increasing intensity of radiation.
Resistance offered by the molecules of a liquid to flow is termed as viscosity.
A process for the industrial production of nitrogen oxide and nitric acid from ammonia and oxygen.
Chemical bonding resulting from the transfer of one or more electrons from one atom or a group of atoms to another.
Compounds containing predominantly ionic bonding.
