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.
