  salt, chemical compound. The Columbia Encyclopedia, Sixth Edition. 2001-05
The chemical formula for an ionic salt is an empirical formula; it does not represent a molecule but shows the proportion of atoms of the elements that make up the salt.
Since a salt may react with a solvent to yield different ions than were present in the salt (see hydrolysis), a solution of a normal salt may be acidic or basic; e.g., trisodium phosphate, Na, dissolves in and reacts with water to form a basic solution.
Salts are often grouped according to the negative ion they contain, e.g., bicarbonate or carbonate, chlorate, chloride, cyanide, fulminate, nitrate, phosphate, silicate, sulfate, or sulfide.

 Salt
In chemistry, a salt is a chemical compound composed of cations (positively charged ions) bound to anions (negatively charged ions).
It is the specific salt sodium chloride, and is described thoroughly in that article.
In general, salts are ionic compounds which form crystals.

 MSN Encarta - Multimedia - Ionic Bonding: Salt
The bond (left) between the atoms in ordinary table salt (sodium chloride) is a typical ionic bond.
In forming the bond, sodium becomes a cation (a positively charged ion) by “giving up” its valence electron to chlorine, which then becomes an anion (a negatively charged ion).
Attracted by electrostatic forces (right), the ions arrange themselves in a crystalline structure in which each is strongly attracted to a set of oppositely charged “nearest neighbors” and, to a lesser extent, all the other oppositely charged ions throughout the entire crystal.

 Patent 5604191
Ionic salt residue on the surface of a substrate material is a reoccurring problem.
Such an exchange of anions could leave salt deposits on the surface because the salt cation and the ligand anion remain separate from the complex compound, and they are not solvent in the organic solvent.
Ionic salt residues are frequently formed with alkali metal and alkaline earth metal cations.

 Salt - Enpsychlopedia
In chemistry, salt is a term used for ionic compounds composed of positively charged cations and negatively charged anions, so that the product is neutral and without a net charge.
Zwitterions are salts that contain an anionic center and a cationic center in the same molecule, examples are the amino acids, many metabolites, peptides, and proteins.
Salts can also form if solutions of different salts are mixed, their ions recombine, and the new salt is insoluble and precipitates (see: Solubility equilibrium).

 Science, Salt Crystal, and Negative Ions - Why Salt Lamps Work
We are not referring to simple rock salt or table salt; because rock salt assumes a crystalline form doesn't mean that it is of the superior quality that we have been talking about here.
Elements within rock salt are not integral to the salt's crystal grid, but instead cling to the outer surfaces and crevices of the crystalline matrix.
A salt crystal manifests a superior structure while rock salt is a cheap alternative to table salt - and is at least a natural, wholesome product.

 Chemical Sciences. Solubility of Ionic Solids in Water
Salts which are less soluble in water than this at room temperature are called slightly soluble salts.
The solubility of an ionic salt depends both upon its cations and its anions, but for simple salts in aqueous solution at room temperature the following general observations are useful.
Sulfate salts are generally highly soluble as well, with more exceptions; calcium, barium, strontium, lead, and mercury (I) sulfates are almost insoluble while silver sulfate is slightly soluble.

At low ionic strength (salt concentrations less than approximately 50 to 100 mM), salts tend to increase the solubility ("salt in") typical globular proteins.
At high ionic strength (salt concentrations higher than 100 mM or so), the solubility of proteins can behave quite differently, depending on the nature of the protein and the type of salt.

(c) rinsing the surface with a fluid to remove the cleaning mixture and solvated ionic residue in a guest/host relationship with said crown ether from said surface.
However, organic solvents having a low polarity are inefficient at solvating ionic salt residue, and when used as the cleaning solution, a significant amount of ionic salt residue remains undissolved.
The cleaning mixture is particularly useful in removing salt deposits from printed circuit boards; however, the cleaning mixture can be used to clean salt deposits from any surface that is otherwise impervious to organic solvents.
