INTRODUCTION Differences between acids and bases An acid-base reaction is based on the reaction involving the ionization of water H2O -> H+ + OH- This means that water can break apart into a hydrogen ion and a hydroxide ion. These two ions can also join together to form a water molecule. When a strong acid is placed in water‚ it will ionize completely‚ and break down into its constituent ions in which one of it a hydrogen ion. When a strong base is placed in water‚ it will ionize
