  • 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...

  • Features of the Scanning Tunneling Microscope

    The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...

  • 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...

Most Popular

Cloud Chamber

A device for observing the paths of speeding particiles as vapor molecules condense on them to form foglike tracks.

Heat of Condensation

The amount of heat that must be removed from one gram of a vapor at it's condensation point to condense the vapour with no change in temperature.

Weak Electrolyte

A substance that conducts electricity poorly in a dilute aqueous solution.

Isotopes

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.

Conjugate Acid-base Pair

In Bronsted-Lowry terminology, a reactant and product that differ by a proton, H+.

Quantum Mechanics

Mathematical method of treating particles on the basis of quantum theory, which assumes that energy (of small particles) is not infinitely divisible.

Amine

Derivatives of ammonia in which one or more hydrogen atoms have been replaced by organic groups.

Heat

A form of energy that flows between two samples of matter because of their differences in temperature.

Titration

A Procedure in which one solution is added to another solution until the chemical reaction between the two solutes is complete, the concentration of one solution is known and that of the other is unknown.

 

Acid

A substance that produces H+(aq) ions in aqueous solution. Strong acids ionize completely or almost completely in dilute aqueous solution. Weak acids ionize only slightly. Chemicals or substances having the property of an acid are said to be acidic.
