Descripción general

Sodium sulfate (Na2SO4) can be obtained directly via precipitation from a saturated solution of Na2SO4 at room temperature (20°C). Its crystallization and growth rates at room temperature (20°C) under various conditions have been investigated. Sodium sulfate can be produced during Leblanc process, from sodium chloride and sulfuric acid.

Aplicación

Sodium sulfate (Na2SO4) may be employed as a reagent for the precipitation of globulins during the estimation of proteins in blood.
