Solution that resists change in pH, contains either a weak acid and a soluble ionic salt of the acid or a weak base and a soluble ionic salt of the base.
- 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'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...
- 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...
- Protein Design: Automated protein discovery and synthesis
In this paper I describe (theoretically) the method(s) of automated protein discovery and synthesis.
- 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...
The dispersing medium of a solution.
Stream of positively charged particles (cations) that moves toward the negative electrode in cathode ray tubes, observed to pass through canals in the negative electrode.
The variations in properties of elements with their position in the periodic table.
Reaction of a substance with water.
Two peaks or bands of about equal intensity appearing close together on a spectrogram.
A sustance that coats the particles of the dispersed phase and prevents coagulation of colloidal particles, an emulsifier.
A large molecule consisting of chains or rings of linked monomer units, usually characterized by high melting and boiling points.
Third Law of Thermodynamics
The entropy of a hypothetical pure, perfect, crystalline sustance at absolute zero temperature is zero.
An oily, slightly water-soluble liquid, C7H6O2, having an almondlike odor: used chiefly in perfumery and in the synthesis of coumarin.
Compounds that contain only carbon and hydrogen.
Substances that flow freely, gases and liquids.
Elements 89 to 103 (between lawrencium and actinium) on the periodic table. Only the first four have been found in nature in appreciable amounts. The remainder have been produced synthetically.
Compartment in which the oxidation or reduction half-reaction occurs in a voltaic cell.
Very weak and very short-range attractive forces between short-lived temporary (induced) dipoles, also called dispersion Forces.
Crystal Field Stabilization Energy
A measure of the net energy of stabilization gained by a metal ion's nonbonding d electrons as a result of complex formation.
A gas formed by boiling or evaporating a liquid.
Electrons in filled sets of s , p orbitals between the nucleus and outer shell electrons shield the outer shell electrons somewhat from the effect of protons in the nucleus, also called screening effect.
The amount of heat required to raise the temperature of one gram of substance one degree Celsius.
A packet of light or electromagnetic radiation, also called quantum of light.
Either the oxidation part or the reduction part of a redox reaction.
