GCSE Chemistry · key term
An ionic compound formed when the hydrogen ions of an acid are replaced by positive ions, such as metal ions.
Used by AQA, Edexcel and OCR
Specification 4.4.1.2, 4.4.2.1, 4.4.2.2 · Paper 1
A compound formed when the hydrogen ions of an acid are replaced by metal ions.
Revise: The Reactivity SeriesWith hydrochloric acid, the salt is a chloride; with sulfuric acid, it is a sulfate.
An ionic compound containing positive ions and negative ions, with no overall electrical charge.
Specification 3.9, 3.11, 3.13, 3.16, 3.19, 3.21 · Paper 1
Revise: Definition of a BaseA base is any substance that reacts with an acid to form a salt and water only.
An ionic compound formed when the hydrogen ions of an acid are replaced by metal ions or ammonium ions.
An ionic compound formed when the hydrogen in an acid is replaced by a metal ion or an ammonium ion.
A compound formed when hydrogen ions from an acid are replaced by metal ions or ammonium ions.
A compound made from positive metal or ammonium ions and negative ions, often formed when the hydrogen ions of an acid are replaced.
Specification C3.3d, C3.3f, C4.1e, C4.1f, PAG 7 · Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
An ionic compound formed when an acid reacts with a base; a salt is not necessarily sodium chloride.
Revise: Neutralisation ReactionsAn acid can react with a base to form two products: a salt and water.
An ionic compound containing positive ions and negative ions.
An ionic compound made of positive and negative ions; a metal salt solution contains dissolved metal ions.
A substance formed when the hydrogen in an acid is replaced by a metal or ammonium ion.
Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
A substance formed when the hydrogen ions of an acid are replaced by metal ions or another positive ion.
Revise: Order of reactivityThe metal atoms remain present in the salt solution.
An ionic compound formed when the hydrogen in an acid is replaced by a metal or another positive ion.
An ionic compound containing a positive ion from a metal or another base and a negative ion derived from an acid.
Use the acid to choose the salt ending: hydrochloric acid forms a chloride; sulfuric acid forms a sulfate.
Take the first part of the salt name from the positive ion and the second part from the acid.
Include the word “only” when recalling the Edexcel definition: a base reacts with an acid to form a salt and water only.
