Overview
Sulfuric Acid 50% is a widely used industrial chemical, with strong acidic properties and excellent solubility in water. It is valued for its versatility and reliability across various sectors where high acid strength is necessary, such as oil refining, metal pickling, pulp and paper manufacturing, and water treatment. It is available as an odorless, colorless to slightly amber solution with a pH of 0.3, which allows operators to efficiently descale, adjust pH, control corrosion, and more. Its lower concentration provides reduced handling risk compared to Sulfuric Acid 93% while remaining highly reactive and effective.
Sodium Hydroxide 50% is available in drums, totes, LTL, and drums.
