    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...

The point of chemical equivalence is indicated by a chemical indicator or an instrumental measurement. When the color changes to the specified color, the titration has reached endpoint. The mole ratio and volume relates the concentration of the solutions. The more the number of moles of the base is used the more number of moles are needed to neutralize. To increase the...
