Solubility is the capacity of a substance to dissolve in a particular solvent. This capacity depends on its physical and chemical properties, including the strength of its electrostatic attraction. It can be measured in g/100 mL of water. Typically, the common threshold for insoluble substances is less than 0.1 g per 100 mL of solvent.
Lithium sulfate is an inorganic salt. It has a white color and is soluble in water. At 20degC, its solubility is 34.8 g of Li2SO4 per 1.00 x 102 g of H2O.
At 320-370degC, its solubility decreases dramatically. The yield of 2-butene is high in this temperature range. A study on lithium salts by Phillips and Perry was carried out at different temperatures. They found that, in equilibrium, the solid phase of the salts is always monohydrate. However, crystallization was not affected by temperature.
Lithium sulfate can be used as a catalyst for an elimination reaction. It is also used in esterification, polymerization, and storage-battery electrolytes.
Lithium sulfate monohydrate is the most common form of this salt. It is slightly soluble in water compared to other alkaline earth metal carbonates.
Lithium chloride is a soluble in water, alcoholics, and glycol. It is an important electrolyte in air-conditioning systems. It has a bitter taste. In medicine, lithium is used as a sedative. Moreover, lithium alloys are used as a reducing agent, heat transfer medium, and as a shielding material for thermal neutrons.
Lithium sulfate anhydrous is also available. It has a density of 2.22 g/cm3. To determine its solubility, it must be dissolved in water that lacks an atmosphere.
