==Key Stage 4==
===Meaning===
A '''Hydrogen ion''', sometimes called a '''proton''', is a [[Positive Ion|positive ion]] of [[Hydrogen]] found in [[acid]] [[solution]]s.
===About Hydrogen Ions===
====Foundation====
: When an [[acid]] [[compound]] [[dissolve]]s in [[water]] it forms '''Hydrogen ions'''.
: '''Hydrogen ions''' are responsible for the [[corrosive]] [[property|properties]] of [[acid]]s.
====Higher====
: As the [[pH]] of a [[solution]] decreases by 1 the '''Hydrogen ion''' [[concentration]] increases by a factor of 10.
===Examples===
HCl(s)
H<sub>2</sub>SO<sub>4</sub>
HNO<sub>3</sub>
H<sub>2</sub>CO<sub>3</sub>
H<sub>3</sub>PO<sub>4</sub>
CH<sub>3</sub>COOH
