Acid
,→Foundation
: [[Acid]]s form from [[Ionic Compound|ionic compounds]] where there is an [[Ionic Bond|ionic bond]] between a [[Hydrogen]] [[ion]] and another part of the [[molecule]].
: When an [[acid]]ic [[compound]] [[dissolve]]s in [[water]] the [[Hydrogen Ion|Hydrogen ion]] becomes dissociated from the [[molecule]] and is free to move separately in the [[solution]].
: The [[Hydrogen Ion|Hyrdrogen Hydrogen ion]]s in an [[acid]] will accept [[electron]]s from any [[metal]] which is higher on the [[Reactivity Series|reactivity series]] than [[Hydrogen]]. This is because those [[metal]]s can lose their [[electron]]s more easily than the [[Hydrogen]] [[atom]].
: The [[acidity]] of an [[acid]] is measured on the [[pH]] scale. The more [[Hydrogen Ion|Hydrogen ions]] in a [[solution]] the lower the [[pH]].
There are several common [[Chemical Reaction|reactions]] of [[acid]]s you should know:
