Identifying a Salt by Creating its Heating Curve Introduction: Solubility is a substance’s ability to be dissolved in a liquid‚ usually water‚ and some substances are more soluble than others. A solution can be saturated‚ unsaturated or supersaturated. Temperature plays a large role in the solubility of substances. For example‚ on table G of the Chemistry reference tables it shows that 10g of KClO3 will dissolve in 100g of water at about 25°C‚ but at about 48°C‚ 20g will dissolve. The higher the
