Acid-Base Titration Using a pH Meter Bradley Holloway and Jennifer Parker Period 6 April 16‚ 2013 Introduction: In chemistry‚ the ability to find molarities of acidic and basic solutions is a convenient way to convert between moles of solute and the volumes of their solutions. Through the process of titration‚ the molarity of these acids and bases can be found to a high level of precision. To begin titration‚ one solution is added to a second solution slowly until a certain point
