acid salt
C1technical/scientific
Definition
Meaning
A salt formed by partial neutralization of a diprotic or polyprotic acid, containing replaceable hydrogen atoms.
In chemistry, a compound resulting from the replacement of only part of the hydrogen ions of an acid by a metal or ammonium ion, capable of further neutralization.
Linguistics
Semantic Notes
The term specifically implies the salt retains acidic properties and can react further with bases.

Examples
By Part of Speech
adjective
British English
- The acid salt properties were evident in the litmus test.
American English
- They studied the acid salt behavior in different solvents.
Examples
By CEFR Level
- Baking powder often contains an acid salt.
- Sodium bicarbonate can react with an acid salt to release carbon dioxide.

Learning
Memory Aids
Mnemonic
Think 'acid salt' = acid not fully 'salted' (neutralized) – it still has some acidic hydrogen left.
Conceptual Metaphor
A halfway house between an acid and a neutral salt.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'кислая соль' – this is a direct equivalent. No trap.
Common Mistakes
- Using 'acid salt' to refer to any acidic compound
- Confusing with 'acidic salt' (same meaning)
- Thinking all salts from weak acids are acid salts (incorrect)

FAQ
Frequently Asked Questions
Yes, in modern chemical nomenclature, they are synonymous terms.
Cream of tartar (potassium hydrogen tartrate) used in baking is a common example.
Typically yes, because its aqueous solution is acidic due to the remaining hydrogen ions.
A normal salt, like sodium chloride, which has no replaceable hydrogen atoms.
