SOLUTE
A solid that dissolves in the solvent
SOLVENT
A liquid that dissolves the solute in it
SOLUTION
A mixture of a solvent and solute
SATURATED SOLUTION
A solution which contains as much dissolved solid as possible at a particular temperature.
SOLUBILITY OF A SOLID (definition)
The maximum mass of a solute that dissolves in 100g of a solvent at a particular temperature.
SOLUBILITY OF A SOLUTE (formula)
solubility of a solute = mass of solute / mass of solvent x 100
SOLUBILITY OF A SOLUTE (unit)
g/100g (grams per hundred grams)
SOLUBILITY INVESTIGATION (What equipment does it need?)
Test tube
Evaporating basin
Thermometer
Water bath
Bunsen burner
SOLUBILITY INVESTIGATION (Which solid can be used?)
KNO3 (potassium nitrate)
SOLUBILITY INVESTIGATION (What is the residue?)
KNO3 crystals after the water evaporated
SOLUBILITY CURVE (purpose)
Solubility curves show how solubility changes over temperature. It increases as the temperature also increases.
