- n. A salt of sulphuric acid. The acid is dibasic, forming two classes of salts—neutral sulphates, in which both hydrogen atoms of the acid are replaced by basic radicals, and acid sulphates, in which only one of the hydrogen atoms is so replaced. Most sulphates are readily soluble in water, while a few, as calcium, strontium, and lead sulphates, are very sparingly soluble, and barium sulphate is insoluble in water and dilute acids. The sulphates are widely and abundantly distributed in nature. Gypsum and anhydrite are calcium sulphates. Epsom salts and Glauber salts, contained in all sea-waters, are magnesium sulphate and sodium sulphate respectively. Barytes or heavy-spar, used on account of its high specific gravity (4.3 to 4.7) as an adulterant and makeweight, is barium sulphate. Anglesite, or lead sulphate, is an ore of lead. Many other sulphates occur in nature in smaller quantity. Of the sulphates artificially prepared may be mentioned sodium sulphate, or salt-cake (made from salt on an enormous scale as the first step in the manufacture of sodium carbonate), and ammonium sulphate (made extensively from gas liquor, and used for preparing other ammonia salts and as a fertilizer). Zinc sulphate, or white vitriol, is used in medicine as an astringent and a tonic, and in larger doses as an emetic. In overdoses it acts as an irritant poison. Copper sulphate, or blue vitriol, is made on an enormous scale, and is used in preparing pigments (Scheele's green, Paris green, etc.), in calico-printing, in electrometallurgy, and in horticulture, particularly by vineyardists, as a fungicide. It is used in medicine, chiefly as a feeble escharotic for exuberant granulations, and as a local stimulant. Aluminium sulphate, called
concentrated alumor sulphate of alumina, is used as a mordant and makeweight and for preparing alums. Ferrous sulphate, or green vitriol, is used as a mordant and for the manufacture of inks, Prussian blue, etc. The alkaloids morphine, atropin, quinine, etc., are generally administered in the form of sulphates.
- To form a deposit of lead sulphate on, as a lead plate or plates of a secondary battery or a secondary cell.
- To convert (red lead used as a coloring material, as on placards) into lead sulphate by means of dilute sulphuric acid.
- To form a sulphate (especially a lead sulphate) deposit.

- n. (Chem.) A salt of sulphuric acid.
- n. a salt or ester of sulphuric acid
“I assume that a kind of alcohol thorinate, an ester comparable with the acid alcohol sulphate, is produced at the surface of the oxide and from this I deduce that this thorinate must, like the sulphate, react with various substances and thus induce, as a catalyst, various reactions with alcohols.”
“Another unusual phosphate derivative had been indicated through the function of ATP in sulphate activation.”
“Sodium sulphate is another natural resource of the Province of Saskatchewan that is being rapidly developed.”
“These boiling springs are said to contain sulphate of lime, carbonic acid, and muriate of soda, and the Indians make salt in their neighbourhood, precisely as they did in the time of Montezuma, with the difference, as Humboldt informs us, that then they used vessels of clay, and now they use copper caldrons.”
“Abrasion is significantly reduced during this time as well -- more synthetic ingredients were added (such as sodium lauryl sulphate, which is a foaming agent), as well as sweeteners.”
“Permanently hard waters are those containing mainly calcium sulphate, which is only precipitated at the high temperatures found in the boiler itself, 300 degrees”
“All clay contains aluminum, in what is known as the sulphate form, and water passing through the clay of the earth thereby becomes purified, because of this element.”
“About one-half of the total products of combustion of black gunpowder of ordinary composition consists of potassium carbonate in a finely divided condition and of potassium sulphate, which is produced chiefly by the burning in the air of potassium sulphide, another production of combustion, as on the outrushing gases it is borne into the air in a fine state of division.”
“A few drops of this mixture will disappear if the lime is equal or in excess of the copper sulphate, that is, it will be neutralized, but if it is not, they will remain a bright purplish red.”
“On cooling and extracting with water, the sulphur will pass into solution as potassium sulphate, which is then filtered off from the insoluble oxides of iron, copper,”
