Study Notes

Solutions and Concentration

  • A concentrated solution is formed when a significant amount of substance dissolves in a minimal volume of water.
  • A dilute solution is created when a small quantity of substance is mixed into a large volume of water.

Process of Dilution

  • To dilute an acid, always add acid to water rather than adding water to acid.
  • This method is important for safety, as adding water to concentrated acid can cause an exothermic reaction, potentially leading to splattering or spills.
