Web19 jun. 2024 · Precipitation of metals as metal sulphides is a practical way to recover metals from mine water. Sulphide precipitation is useful since many metals are very sparingly soluble as sulphides. Precipitation is also pH dependent. This article investigates the precipitation of metals individually as sulphides and assesses which metals are … Solubility occurs under dynamic equilibrium, which means that solubility results from the simultaneous and opposing processes of dissolution and phase joining (e.g. precipitation of solids). The solubility equilibrium occurs when the two processes proceed at equal and opposite rates. The term … Meer weergeven In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution. Meer weergeven Solubility is defined for specific phases. For example, the solubility of aragonite and calcite in water are expected to differ, even though they … Meer weergeven A popular aphorism used for predicting solubility is "like dissolves like" also expressed in the Latin language as "Similia … Meer weergeven The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two.
