HYDROSULPHITE, AQUEOUS Chemical compatibility with O-rings, rubbers, & plastics

Aqueous hydrosulphite, commonly known as sodium dithionite, is a reducing agent used in various industrial applications. It is employed in textile processing for bleaching and dyeing, in the paper industry for pulp bleaching, and in water treatment as a reducing agent. Aqueous hydrosulphite is also used in chemical synthesis and environmental remediation. Despite its utility, it poses health hazards, including respiratory and skin irritation. It can decompose to release sulfur dioxide, which is toxic and corrosive. Proper handling, storage, and safety measures, including adequate ventilation and personal protective equipment, are essential to ensure safe usage and prevent exposure.
