#Wash a [[Volumetric Pipette|volumetric pipette]] and [[burette]] with [[Distilled Water|distilled water]] then wash the [[Volumetric Pipette|volumetric pipette]] with the 0.1[[Molarity|M]] [[Sodium Hydroxide]] and the [[burette]] with 0.08[[Molarity|M]] [[Sulphuric Acid]] to avoid contamination from previous [[experiment]]s.
#Measure 25ml of [[Sodium Hydroxide]] using the [[Volumetric Pipette|volumetric pipette]].
#Add the [[Sodium Hydroxide]] to a [[Conical Flask|conical flask]] and then add a few drops of [[Methyl Orange]].
#Fill the [[burette]] with 0.08[[Molarity|M]] [[Sulphuric Acid]].
#Add the [[Sulphuric Acid]] to the [[Sodium Hydroxide]] one drip at a time, swirling the [[Conical Flask|conical flask]] constantly to mix the [[reactant]]s thoroughly.
#Repeat until the [[Methyl Orange]] turns from yellow to red [[pH Indicator|indicating]] the [[solution]] is [[Neutral (Chemistry)]].
#Record the [[Volume (Space)|volume]] of [[Sulphuric Acid]] added to the [[Conical Flask|conical flask]].
#Repeat the [[experiment]] at least 3 times to produce an [[Mean Average|average]].
