Sodium sulfate | Na2SO4 - PubChem

Sodium Sulfate Anhydrous is the anhydrous, sodium salt form of sulfuric acid.Sodium sulfate anhydrous disassociates in water to provide sodium ions and sulfate ions. Sodium ion is the principal cation of the extracellular fluid and plays a large part in the therapy of fluid and electrolyte disturbances. Sodium sulfate anhydrous is an electrolyte replenisher and is used in isosmotic solutions ...

New Eco-Friendly Xanthate-Based Flotation Agents

An optimal laboratory two-step procedure was developed for sodium/potassium O-alkyl carbonodithioate (sodium/potassium alkyl xanthates) production in the form of aqueous solutions. Sodium isopropyl xanthate (Na-iPrX), as the most effective salt in a real ore flotation process, was also produced at an industrial level and introduced as a collector for copper ores.

Comparatively Speaking: Sulfate vs. Sulfonate

They include things like sodium lauryl sulfate and sodium laureth sulfate. The presence of the C-O-S bond makes these materials hydrolyze at low pH values, producing alcohol and inorganic sulfate. Sulfates are stable in base at high pH values and, if ethoxylated to a relatively high level, produce low foaming alkali soluble surfactants.
