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.
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 ...
Place a stub template at the very end of the article, after the "External links" section, any navigation templates, and the category tags. As usual, templates are added by including their name inside double braces, e.g. {{Organic-compound-stub}} .
More than one stub template may be used, if necessary, though no more than four should be used on any article. Place a stub template at the very end of the article, after the "External links" section, any navigation templates, and the category tags. As usual, templates are added by including their name inside double braces, e.g. {{Salt-stub}}.
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 template is used on approximately 7,500 pages and changes may be widely noticed. Test changes in the template's /sandbox or /testcases subpages, or in your own user subpage . Consider discussing changes on the talk page before implementing them.
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 °.
