How do you read a solubility curve?
Trace the solubility of a substance with increasing temperature.
- The curved line represents saturation.
- Below the curve, the solution is unsaturated.
- Above the curve the solution is supersaturated. This means there is more solute than the solution can hold.
What causes solubility?
Solubility is the ability of a solid, liquid, or gaseous chemical substance (referred to as the solute) to dissolve in solvent (usually a liquid) and form a solution. The solubility of a substance fundamentally depends on the solvent used, as well as temperature and pressure.
How is solubility written?
When water is the solvent, solubility can be expressed in relative volume, commonly as grams of solute per 100 grams of solvent. If water is the solvent, for example, this is expressed as grams of solute per 100 grams of water. This expression of solubility considers the mass of the solvent before the solute is added.
How do you find the solubility limit?
Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .
