Acid base titration: The chemical reaction involved in acid-base titration is known as neutralisation reaction. It involves the combination of H 3 O + ions with OH-ions to form water. In acid-base titrations, solutions of alkali are titrated against standard acid solutions. One involves water. I'll leave it up to you to decide which. Are there any cons for using non-aqueous systems for titration? Safety issues, water can be difficult to remove from organic solvents, theory of acid-base equilibrium in non-aqueous solvents is very complex, and calculations are more difficult (most titration curves have to be constructed experimentally). Nope. Acid or Alkali molecules can not ionize/dissociate in ROH. So you will be mixing neutral solutions in your fancy burettes and pipettes, if you use alcohol as a solvent.
