Cautions while adding acid to water

  • Reaction of acid or base with water leads to the decrease in the concentration of ions (H3O+/OH) per unit volume. This process is known as dilution.
  • The procedure of dissolving acid or base in water is highly exothermic reaction.
  • The acid needs to be added slowly to water with constant stirring.

  • Adding water to concentrated acid generates tremendous heat causing the mixture to splash out and can even cause burns.

    • The beaker used for the reaction may also break due to the generation of excessive indigenous heating.
