A dry cell in which the anode is Cd, the cathode is NiO2, and the electrolyte is basic.
- 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...
- 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.
- 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...
A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).
Lewis Dot Formula (Electron Dot Formula)
Representation of the core of a molecule, ion or formula unit by showing atomic symbols and only outer shell electrons.
The oxide of a metal that reacts with water to form a base.
Any kind of matter all specimens of which have the same chemical composition and physical properties.
Half-cells in which the oxidized and reduced forms of a species are present at unit activity, 1.0M solutions of dissolved ions, 1.0atm partial pressure of gases, and pure solids and liquids.
Adhesion of a species onto the surfaces of particles.
Coordination Compound or Complex
A compound containing coordinate covalent bonds.
Reactions that do not go to completion and occur in both the forward and reverse direction.
Theory of reaction rates that states that effective collisions between reactant molecules must occur in order for the reaction to occur.
A gas filled tube which discharges electriaclly when ionizing radiation passes through it.
A small, calibrated electroscope worn by laboratory personnel and designated to detect and measure incident ionizing radiation or chemical exposure.
Combination of symbols that indicates the chemical composition of a substance.
A compound formed by interaction of sucrose with a metallic oxide, usually lime, and useful in the purification of sugar.
A device used to measure the densities of liquids and solutions.
Radius of an atom.
Metal with low ionization energy that loses electrons readily to form cations.
Solubility Product Principle
The solubility product constant expression for a slightly soluble compound is the product of the concentrations of the constituent ions, each raised to the power that corresponds to the number of ions in one formula unit.
A fairly strong dipole-dipole interaction (but still considerably weaker than the covalent or ionic bonds) between molecules containing hydrogen directly bonded to a small, highly electronegative atom, such as N, O, or F.
The process by which solvent molecules pass through a semipermable membrane from a dilute solution into a more concentrated solution.
H2SO4: colorless, oily liquid, boiling point 330C. A 96 percent solution is used in the laboratory.
Fire Hazard: This is a very powerful, acidic oxidizer which can Ignite or even explode on contact with many materials, i.e. acetic acid ,acetone+ HNOs, alcohols, + H202, NH4OH, HCL, NaOH, and others.
Sulfuric acid has a wide range of uses and plays a part in the production of nearly all manufactured goods.
