Acetate \Ac"e*tate\, n. [L. acetum vinegar, fr. acere to be sour.] (Chem.) A salt formed by the union of acetic acid with a base or positive radical; as, acetate of lead, acetate of potash.
Douglas Harper's Etymology Dictionary
1827, "salt formed by combining acetic acid with a base," from Latin acetum "vinegar" (see acetic) + chemical suffix -ate (3). As a type of synthetic material, it is attested from 1920, short for acetate silk, etc.

Wikipedia
An acetate is a salt formed by the combination of acetic acid with an alkaline, earthy, or metallic base. "Acetate" also describes the conjugate base or ion (specifically, the negatively charged ion called an anion) typically found in aqueous solution and written with the chemical formula CHO. The neutral molecules formed by the combination of the acetate ion and a positive ion (called a cation) are also commonly called "acetates" (hence, acetate of lead, acetate of aluminum, etc.). The simplest of these is hydrogen acetate (called acetic acid) with corresponding salts, esters, and the polyatomic anion CHCO, or CHCOO.
Most of the approximately 5 billion kilograms of acetic acid produced annually in industry is used in the production of acetates, which usually take the form of polymers. In nature, acetate is the most common building block for biosynthesis. For example, the fatty acids are produced by connecting the two carbon atoms from acetate to a growing fatty acid.
Acetate can refer to:
- Acetate, a salt or ester of acetic acid
- Cellulose acetate, the acetate ester of cellulose
- Acetate disc, disc used in record production
- Projector transparencies are sometimes referred to as acetates, or acetate sheets
Usage examples of "acetate".
The addition of a little sodium acetate to the solution after the final neutralising has a good effect.
A special test for sulphide may be made by adding a drop or two of solution of acetate of lead to four or five c.
This is specially apt to occur when sodium acetate is present, although it may also be due to excessive dilution.
This shows that ferric acetate liberates iodine under the conditions of the assay.
Add 20 grams of sodium acetate, warm, and precipitate the lead with a dilute solution of potassium chromate.
Next add a strong solution of sodium acetate, until the solution ceases to darken on further addition, then dilute with water to half a litre.
Filter off the precipitate and wash with hot water containing a little sodium acetate, dissolve it off the filter with hot dilute hydrochloric acid, add ammonia in excess, and pass sulphuretted hydrogen for five minutes.
The precipitate of ammonic-magnesic phosphate is filtered off, dissolved, and titrated with uranium acetate, using the same standard solution as is used in the arsenic assay: 0.
The precipitation of lead from acid solutions with sulphuric acid, and the solubility of the precipitate in ammonium acetate, distinguishes it from all other metals.
The addition of potassium chromate to the acetate solution reprecipitates the lead as a yellow chromate.
If the volumetric method is to be used, the lead sulphate should be dissolved out with a solution of sodium acetate instead of with the ammonium salt solution.
If the lead is present as sulphate in sodic acetate solution, it is well to render it distinctly alkaline with ammonia.
When the lead in the assay has been separated as sulphate and dissolved in sodic acetate, less chromate is apparently required, and in this case it will be necessary to precipitate the lead in the standard with an equivalent of sodic sulphate and redissolve in sodic acetate just as in the assay.
After cooling, a solution of sodium acetate is added until the colour of the solution is no longer darkened.
The precipitate is filtered quickly through a large filter, and washed with hot water containing a little acetate of soda.
