===Meaning===
[[Titration]] is an [[Experimental Technique|experimental technique]] used to [[measure]] the exact [[Volume (Space)|volume]]s of [[acid]] and [[alkali]] needed to have a complete [[Neutralisation]] [[Chemical Reaction|reaction]].
 
===About Titration===
: During a [[titration]] one of the [[solution]]s is a fixed [[Volume (Space)|volume]] and the other is is added as needed and [[measure]]d as [[precision|precisely]] and [[accuracy|accurately]] as possible.
: To obtain a fixed [[Volume (Space)|volume]] a [[Volumetric Pipette]] is used.
: To [[measure]] the [[Volume (Space)|volume]] being added a [[Burette]] is used.
 
===Method===
For a fixed [[Volume (Space)|volume]] of [[alkali]] and a [[measure]]d [[Volume (Space)|volume]] of [[acid]].
#Wash the [[Volumetric Pipette|volumetric pipette]] and [[burette]] with [[Distilled Water|distilled water]] then wash the [[Volumetric Pipette|volumetric pipette]] with the [[alkali]] and the [[burette]] with the [[acid]] to avoid contamination from previous [[experiment]]s.
#Measure and record a fixed [[Volume (Space)|volume]] of [[alkali]] using the [[Volumetric Pipette|volumetric pipette]].
#Add the [[alkali]] to a [[beaker]] and then add a few drops of [[pH Indicator]].
#Fill the [[burette]] with [[acid]].
#Add the [[acid]] to the [[alkali]] one drip at a time, swirling the [[beaker]] constantly to mix the [[reactant]]s thoroughly.
#Repeat until the [[pH Indicator]] shows the [[solution]] is [[Neutral (Chemistry)|neutral]].
#Record the [[Volume (Space)|volume]] of [[acid]] added to the [[beaker]].
#Repeat the [[experiment]] at least 3 times to produce an [[Mean Average|average]].
