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 ions of an acid are replaced by metal ions or other positive ions.

In a metal–acid reaction, metal ions replace these hydrogen ions to form a salt, while hydrogen gas is released.

An ionic compound formed when the hydrogen ions of an acid are replaced by positive ions, such as metal ions.

Acids react with several different types of substance. These reactions all produce salts, but their other products depend on what reacts with the acid. A salt is an ionic compound formed when the hydrogen ions of an acid are replaced by metal ions or ammonium ions.

A substance formed when the hydrogen in an acid is replaced by a metal or ammonium ion.

Use the acid to choose the salt ending: hydrochloric acid forms chlorides; sulfuric acid forms sulfates.

For these reactions, iron forms Fe²⁺ ions, so the salts are iron(II) chloride, FeCl₂, and iron(II) sulfate, FeSO₄.

Name the salt using the metal first and the acid-derived ending second: chloride, nitrate or sulfate.
