SOLUBILITY Some salts are sparingly soluble (< 0.1 M) some-mes referred to as ‘insoluble’. Precipita6on and Solubility of ionic salts and their equilibrium in water 2 Solubility Solubility: quan-ty of a substance that dissolves to form a saturated solu-on Solubility: g/L Molar solubility: mole/L Some salts are very soluble (> 0.1 M). Recall solubility rules (Chapter 4.2). MA(s) M + (aq) + A (aq) MJ Bojan
