Sodium Sulfate - Anhydrous

Sodium sulfate is the sodium salt of sulfuric acid. Sodium sulfate is chemically very stable, being unreactive toward most oxidising or reducing agents at normal temperatures. It is a neutral salt, which forms aqueous solutions with pH of 7. The neutrality of such solutions reflects the fact that Na2SO4 is derived, formally speaking, from the strong acid sulfuric acid and a strong base sodium hydroxide. Sodium sulfate reacts with an equivalent amount of sulfuric acid to give an equilibrium concentration of the acid salt sodium bisulfate
