Sodium sulfate Na2SO4 PubChem

Sodium sulfate is a strong contributor to the rate of corrosion. For example, in water with 400 mg/l of alkalinity (as CaCO3) at pH 7, the corrosion rate will be zero at 200 mg/l of Na2SO4, but when the concentration of sodium sulfate

Effects of sodium sulfate concentration on the sulfate

1995-8-1  Sulfate concentration in water is an important factor governing the extent of damage. Concentration of 0-150 ppm, 150-1500 ppm, 1500-10000 ppm and above 10000 ppm can be classified as mild, moderate, severe and very severe respectively (l). Reactions of sodium sulfate with Ca (OH)2 and monosulfate produce gypsum and ettnngite (1,2,3,4,5,6).
