Created page with "==Key Stage 4== ===Meaning=== A '''Hydrogen ion''', sometimes called a '''proton''', is a positive ion of Hydrogen found in acid solutions. ===Ab..."

New page

==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)
H2SO4
HNO3
H2CO3
H3PO4
CH3COOH
