PHOTOCHEM Sodium Metabisulfite per 500gm (05534-0500)
Sodium Metabisulfite (chemical formula: Na₂S₂O₅) is a white, crystalline powder with a sharp sulfur smell. It is commonly used as a preservative, antioxidant, and reducing agent in food, wine-making, and laboratory settings. In photography, sodium metabisulfite is used primarily as a preservative and anti-oxidant in developer and fixer solutions. It helps prevent the oxidation of key developing agents, such as Metol and Hydroquinone, thereby extending the life and effectiveness of photographic chemicals. It is also used in acid stop baths and clearing baths, particularly in black-and-white processing. Its stabilizing properties make it essential in maintaining solution consistency and image quality, especially during long darkroom sessions or when storing mixed chemicals for extended periods.
