1.5C: Know What is Meant by the Term Solubility in the Units g Per 100g of Solvent

SOLUBILITY: How much of a substance will dissolve in a given volume of a solvent (shown in the units of g per 100g of solvent)

s

• If a substance is soluble, it will dissolve in a given amount of solvent (liquid)
• Solubility increases as temperature and pressure increases
