PHOTOCHEM Sodium Sulphite per 1 kg (05537-1000PP)
Sodium Sulphite (chemical formula: Na₂SO₃) is a white, water-soluble powder commonly used as a preservative and antioxidant in various chemical processes. In photography, sodium sulphite plays a crucial role as a preservative in developer solutions, particularly in black-and-white processing. It helps prevent the oxidation of developing agents like Metol and Hydroquinone, thereby extending the life of the developer and maintaining image quality. Sodium sulphite also acts as a mild clearing agent, helping to remove residual fixer from film and prints during the washing process, which improves their archival stability. Its stabilizing properties make it an essential component in ensuring consistent and long-lasting photographic results in traditional darkroom work.
