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. Electrolysis is used in industry to separate the elements of a compound. Its applications include making chlorine gas (Cl 2) or pure sodium (Na) metal. Pure sodium is used in street lamps to give off a bright yellow light. U1.16 Unit 5 Industrial Chemistry.

Sulfate concentrations lower than 100 mg/L are typically achieved using this process, with the final concentration dependent upon the reagent dosage and residence time. The CESR process is simpler and less expensive than other sulfate-removal technologies such as reverse osmosis, ion exchange or sodium aluminate addition, and is more effective. Products Of Electrolysis - Products of electrolysis depend on the nature of material being and the type of electrodes being used .If the electrode is inert, it does not participate in the chemical reaction and acts only as source or sink for electrons. On the other hand, if the electrode is reactive, it participates in the electrode reaction Electrolysis Electrolysis is an electrochemical process by which current passes from one electrode to another in an ionized solution that is an electrolyte.

Logic & Solution:. Electrolysis of water produces hydrogen and oxygen in a ratio of 2 to 1 respectively. 2 H 2 O(l) → 2 H 2 (g) + O 2 (g); E 0 = +1.229 V. The energy efficiency of water electrolysis varies widely. The efficiency of an electrolyzer is a measure of the enthalpy contained in the hydrogen (to undergo combustion with oxygen or some other later. Due to the easier electrolysis of water containing 1 H rather than 2 H (D) or 3 H (T), electrolysis can be used for producing water with reduced or enriched isotopic composition. Local inhomogeneities of surface tension in the produced gas bubbles may be caused by temperature or altered material concentration gradients at the interface Solid-liquid equilibria in the quinary system NaCl + NaOH + Na2CO3 + Na2SO4 + H2O at 363.15 K were measured by the wet residue method, and the equilibrium solid phases and solubilities of saturated solutions were determined experimentally.
