View source for Acid + Metal Oxide → Metal Salt + Water

==Key Stage 3==
===Meaning===
[[Acid + Metal Oxide → Metal Salt + Water]] is the general [[Chemical Equation|equation]] for a [[neutralisation]] [[Chemical Reaction|reaction]] between a [[Metal Oxide]] and an [[acid]].

===About 'Acid + Metal Oxide' Reactions===
: '''[[Acid]] + [[Metal Oxide]]''' [[Chemical Reaction|reactions]] are [[exothermic]] so the there will be a [[temperature]] rise.
: The [[Chemical Reaction|reaction]] between a [[Metal Oxide]] and an [[acid]] produces [[water]]
: The [[Chemical Reaction|reaction]] between a [[Metal Oxide]] and an [[acid]] produces a [[Metal Salt]].

===Examples===
'''[[Acid]] + [[Metal Oxide]] → [[Metal Salt]] + [[Water]]'''
: [[Hydrochloric Acid]] + [[Lithium Oxide]] → [[Lithium Chloride]] + [[Water]]
: [[Hydrochloric Acid]] + [[Iron Oxide]] → [[Iron Chloride]] + [[Water]]

: [[Sulphuric Acid]] + [[Potassium Oxide]] → [[Potassium Sulphate]] + [[Water]]
: [[Sulphuric Acid]] + [[Aluminium Oxide]] → [[Aluminium Sulphate]] + [[Water]]

: [[Nitric Acid]] + [[Magnesium Oxide]] → [[Magnesium Nitrate]] + [[Water]]
: [[Nitric Acid]] + [[Titanium Oxide]] → [[Titanium Nitrate]] + [[Water]]

===About 'Acid + Metal Oxide' Reactions===
: '''[[Acid]] + [[Metal Oxide]]''' [[Chemical Reaction|reactions]] are [[exothermic]] so the there will be a [[temperature]] rise.
: '''[[Acid]] + [[Metal Oxide]]''' [[Chemical Reaction|reactions]] occur when the [[Metal]] in the [[Metal Oxide]] is more [[Reactivity|reactive]] than [[Hydrogen]]. This means the [[metal]] can lose [[electron]]s more easily than [[Hydrogen]] can. 
: During an '''[[Acid]] + [[Metal Oxide]]''' [[Chemical Reaction|reaction]] the [[Hydrogen Ion (Chemistry)|H<sup>+</sup> ions]] gain an [[electron]] from the [[Metal]] and [[bond]] with the [[Oxygen]] to [[product|produce]] [[water]].
