What is Solubility?
The maximum amount of a solute that can dissolve in a given amount of solvent at a specified temperature. Expressed as g/100 mL or mol/L. Solubility depends on temperature (usually increases for solids, decreases for gases) and pressure (important for gases).

Low solubility does not mean low toxicity — many sparingly soluble compounds are highly toxic (e.g., lead sulfate, mercuric sulfide). Barium compounds (BaSO₄ safe for X-rays; BaCl₂ highly toxic). Always check toxicity data regardless of solubility. Precipitation of toxic heavy metals during wastewat…
