Study Notes

Solubility

  • Polar compounds dissolve in polar solvents, this is called the "like dissolves like" rule.
  • Nonpolar compounds dissolve in nonpolar solvents.
  • Solubility can be expressed as soluble (S) or partially soluble (PS) or insoluble.

Density

  • Density is defined as mass per unit volume, and is typically measured in grams per millilitre (g/mL).
  • The density of water at 25°C is 0.9970 g/cm3.
  • 1 mL is equivalent to 1 cm3, so these units can be interchanged.
