Question
Why an acid should be added to water for dilution?
✓

Answer

  • When water is added to a concentrated acid for dilution, the heat generated may cause the mixture to splash out and may cause burns.
  • The glass container may also break due to excessive local heating
  • Therefore, for dilution of concentrated acid, instead of adding water to acid, acid is added slowly to water with constant stirring.
  • Hence, liberated heat energy during dilution will spread in water and does not cause harm.
