Use the Standard Grade textbook to find definitions for the following: Solute: Solvent: Solution:
2
Aim: Aim: To investigate the relationship between solubility and bonding Method: 2ml acetone + camphor 2ml acetone + paraffin 2ml acetone + copper (II) sulphate 2ml acetone + potassium permanganate
3
Results: CompoundFormula Solubility in Water (Polar covalent) Acetone (covalent) Sodium Chloride (Ionic) CamphorC 10 H 16 O (Covalent) ParaffinC 20 H 42 (Covalent) Copper sulphate CuSO 4 (Ionic) Potassium permangante KMnO 4 (Ionic)
4
Conclusion: In general, ionic solids dissolve in water and ionic solvents (Ionic substances completely break up in water) covalent solids dissolve in covalent solvents. ‘like dissolves like’
