Meaning and Definition
A chemical compound that is a basic acetate, typically containing a metallic element with some of its valence satisfied by hydroxyl (OH) groups and some by acetate (CH3COO-) groups.
In technical chemistry, a salt containing both hydroxide and acetate ions bound to the same metallic cation, often formed by the partial neutralisation of acetic acid with a base, or by the hydrolysis of a normal acetate. The most common example is the solution of lead subacetate used historically in medicine and industry.

FAQ
Frequently Asked Questions
No, it is a highly specialised technical term from chemistry and historical medicine, very rarely encountered outside those fields.
In this chemical context, 'sub-' indicates a 'basic' salt, meaning the compound contains hydroxide (OH-) ions in addition to acetate ions. It denotes a partially neutralised form.
The most historically notable example is lead subacetate, which was used in 'Goulard's Extract' as an astringent and in certain industrial processes.
Many subacetates, like lead subacetate, are toxic and pose significant health and environmental hazards. They should only be handled with proper training, safety equipment, and disposal protocols.
