Sodium bisulfate Cas 7681-38-1

Acidity Regulators: Food-grade acidifiers and leavening agents, replacing citric acid and phosphoric acid; used in baking, canning, meat products, and pet food to adjust pH and inhibit microorganisms.

Water Treatment Industry:pH lowering agent for swimming pools and landscape water, safer than hydrochloric acid; neutralizes alkalinity and inhibits scale in circulating cooling water; regulates pH in aquaculture water.

Detergents and Daily Chemicals: Main ingredient in solid acidic cleaning agents, removing scale, urine scale, tile rust, and carbonate blockages in pipes; core component of toilet cleaners and descaling agents.

Industrial Chemicals: Acidic catalyst for organic synthesis; pH buffer for dyeing and printing baths; pH regulator for leather tanning; acidity control agent for electroplating solutions; raw material for sulfate preparation.

Metal Surface Treatment: Acid pickling and rust removal for steel and aluminum, gently removing oxide scale, low-corrosion substrates.

Other Uses: Soil acidification amendment (adjusting acidity in alkaline soils); feed additive; acidic reagent for laboratory analysis.
