| hexazonium salts | Diazonium salt's that contain three azo groups. (05 Mar 2000) |

| smelling salts | A hydroalcoholic solution containing approximately 2% ammonia and 4% ammonium carbonate and the aromatics: lemon oil, lavender oil, and myristica oil. Used mainly by inhalation to produce reflex stimulation in persons who have fainted or are at risk of syncope. Synonym: sal volatile, smelling salts. (05 Mar 2000) |
| sulfonium salts | Compounds containing sulfur covalently linked to three moieties; e.g., RS+(R')R''', such as S-adenosyl-l-methionine. (05 Mar 2000) |
| diazonium salts | Salt's of a theoretical base R-≡N or R-N==NOH useful in histochemistry to demonstrate tissue phenols and aryl amines or with enzymatically released naphthols and naphthylamines to form the chromophore azo group -N==N-; diazonium salt's contain only one R-≡N group, tetrazonium salt's contain two, and hexazonium salt's contain three; examples include fast garnet GBC base and naphthol AS.

| tetrazolium salts | <chemical> Quaternary salts derived from tetrazoles. They are used in tests to distinguish between reducing sugars and simple aldehydes, for detection of dehydrogenase in tissues, cells, and bacteria, for determination of corticosteroids, and in colour photography. Pharmacological action: indicators and reagents. (12 Dec 1998) |
| tetrazonium salts | Diazonium salt's that contain three azo groups. (05 Mar 2000) |
| effervescent salts | Preparations made by adding sodium bicarbonate and tartaric and citric acids to the active salt; when thrown into water the acids break up the sodium bicarbonate, setting free the carbonic acid gas. (05 Mar 2000) |
| Epsom salts | <chemical> Sulfuric acid magnesium salt (1:1). A small colourless crystal used as an anticonvulsant, a cathartic, and an electrolyte replenisher in the treatment of preeclampsia and eclampsia. It causes direct inhibition of action potential in the myometrial muscle cells. Excitation and contraction are uncoupled, which decreases the frequency and force of contractions. Pharmacological action: anticonvulsants, cathartic, tocolytic agents. Chemical name: Sulfuric acid magnesium salt (1:1) (12 Dec 1998) |
