Solubility is often expressed as the mass of solute per volume (g/L) or mass of solute per mass of solvent (g/g), or as the moles of solute per volume (mol/L). Even for very soluble substances, however, there is usually a limit to how much solute can dissolve in a given quantity of solvent. In general, the solubility of a substance depends on ...

Watercoal interactions are dominant factors that affect water quality in coal mines. Using lixiviation, the effects of watercoal interactions on pH, salinity, and hazardous elemental enrichment in coal mine water and associated trends were simulated and analyzed. The salinity and hazardous element contents were low in the alkaline solution filtrate. However, the salinity and contents of ...

The effect is particularly well seen with lime. Minute amounts of calcium hydroxide enhance the solubility of quartz, but large amounts almost completely depress it. Lime is not very soluble in water, but it is soluble enough to give a solution which is centinormal in alkalinity and has a pH of about 12.
