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.

Molecular Weight

The mass of one molecule of a nonionic substance in atomic mass units.

Flammable

A liquid as defined by NFPD and DOT as having a flash point below 37.8°C (100°F).

Cation

A positive ion, an atom or group of atoms that has lost one or more electrons.

History of diamonds

Diamond has been known for about 5 thousand years. Historians suggest that it was first discovered in India in river placers. It has long been credited with magical properties, and the largest famous crystals and products from them are shrouded in a halo of mystical legends.

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 so important and why you should always use the chemicals that you own for their intended purpose only. Otherwise, the repercussions could be disastrous to say the least. There are specific things that you and those around you should do when handling, storing or using chemicals in nearly every form.

Buffer Solution

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.

D -Transition elements (metals)

B Group elements except IIB in the periodic table, sometimes called simply transition elements EX. Fe, Ni, Cu, Ti .
For further information see Metals.

Base

A substance that produces OH (aq) ions in aqueous solution. Strong soluable bases are soluble in water and are completely dissociated. Weak bases ionize only slightly.

Osmosis

The process by which solvent molecules pass through a semipermable membrane from a dilute solution into a more concentrated solution.
