Salt/common salt – a mineral, sodium chloride, NaCl, formed by evaporating seawater (impure form). Salt of tartar – potassium carbonate; also called potash. Salt of hartshorn/sal volatile – ammonium carbonate formed by distilling bones and horns. Tin salt – hydrated stannous chloride; see also spiritus fumans, another chloride of tin.
In chemistry, a salt or ionic compound is a chemical compound consisting of an assembly of positively charged ions and negatively charged ions , [1] which results in a compound with no net electric charge (electrically neutral). The constituent ions are held together by electrostatic forces termed ionic bonds.
This is a list of common chemical compounds with chemical formulae and CAS numbers, indexed by formula. This complements alternative listing at list of inorganic compounds. There is no complete list of chemical compounds since by nature the list would be infinite.
For the special case of the formation of a compound from the elements, the change is designated ΔH form and is a weak function of temperature. Values of Δ H form are usually given where the elements and compound are in their normal standard states, and as such are designated standard heats of formation, as designated by a superscript °.
Chemical formulas can be used to describe the relative amounts of elements present in a compound. For example, the chemical formula for water is H 2 O: this means that each molecule of water is constituted by 2 atoms of hydrogen (H) and 1 atom of oxygen (O). The chemical composition of water may be interpreted as a 2:1 ratio of hydrogen atoms ...
Frémy's salt is a chemical compound with the formula (K 4 [ON(SO 3) 2] 2), sometimes written as (K 2 [NO(SO 3) 2]). It is a bright yellowish-brown solid, but its aqueous solutions are bright violet. It is a bright yellowish-brown solid, but its aqueous solutions are bright violet.
Kuzel's salt structure is composed of the perfect intercalation of the Friedel's salt structure and the monosulfoaluminate structure (the two end-members of the studied bi-anionic AFm compound). The structural properties of Kuzel's salt explain the absence of extended chloride to sulfate or sulfate to chloride substitution.
