What is a Sodium bisulfate (NaHSO₄)?

Sodium bisulfate (NaHSO₄) is a colorless or white crystalline or powdery compound that is a type of sodium salt of sulfuric acid. It is formed when sulfuric acid releases a hydrogen ion (H⁺) and binds with a sodium ion (Na⁺). Sodium bisulfate is widely used in industries such as chemical manufacturing, cleaning, pharmaceuticals, and water treatment. This compound is highly acidic and is used in various chemical reactions as an oxidizing agent or neutralizing agent. It is also commonly employed for water treatment, such as adjusting the pH of household water or swimming pools, and as a cleaning agent. Sodium bisulfate has the property of producing an acidic solution, making it useful for lowering pH levels, especially in water and pool maintenance.

Due to its strong acidity, sodium bisulfate can be irritating to the skin and eyes, so protective equipment should be worn when handling it.
