Solutions

- Some substances dissolve in liquid to form a SOLUTION.

- In solution, dissolved substances break up so light can pass through. This is why solutions are transparent.

- Solution either coloured or colourless depending on substances in it.

-Liquid in solution called SOLVENT.

- Substance dissolved called SOLUTE.

- Water dissolves many solids, some gasses and some liquids.

- Substance that dissolves in solvent is SOLUBLE.

- Substances that don't dissolve are INSOLUBLE.

- When solution formed, there is CONSERVATION OF MASS. MASS of SOLUTION = MASS of DISSOLVED SUBSTANCE + MASS OF LIQUID AT START.

- Limit to how much solute you can dissolve into particular volume of solvent. All extra solute will sink. SATURATED.

- Solubility depends on solvent, temperature and solute.
