Study Notes
Solubility Ratios
- Solubility of a substance can be expressed as a ratio between the amount of solute and solvent at a given temperature.
- Example: 100 g of saturated solution contains 100 g of solute and 300 g of solvent, so the solubility is 100:300 or 1:3.
Solubility Calculations
- If 100 g of a saturated aqueous solution leaves a residue of 25 g after evaporation, the solubility is 1:3 or 1 g in 3 g or mL of water.
- If a saturated aqueous solution contains 25 g of a substance in each 100 mL, and the specific gravity of the solution is 1.15, the solubility is 1:3.6 or 1 g in 3.6 g or mL of water.
- If a saturated aqueous solution has a strength of 20% (w/w), the solubility is 1:4 or 1 g in 4 g or mL of water.
Solubility Examples
- One gram of boric acid is soluble in 18 mL of water, so the percentage strength (w/w) of a saturated aqueous solution is 5.26%.
- One gram of boric acid is soluble in 18 mL of alcohol, so the percentage strength (w/w) of a saturated alcoholic solution is 6.49%.
- The solubility of a substance is 1 g in 3 mL of water. To make 200 mL of a saturated solution, 59.5 g of the substance and 178.5 mL of water should be used.
Solubility of Sucrose
- If the percentage strength (w/v) of a saturated aqueous solution of sucrose is 85%, and the specific gravity of the solution is 1.313, the solubility of sucrose in water is 1:0.547.
Solubility of Unknown Substances
- If a saturated aqueous solution contains 30 g of a substance in each 100 mL, and the specific gravity of the solution is 1.1, the solubility is 1:2.66.
- If 20 g of a substance are dissolved in 11 mL of water, and the volume of the resulting solution is 23.5 mL, the solubility is 1:0.55, and the percentage strength (w/w) and (w/v) of the solution are 64.5% and 85.1%, respectively.
