Sodium hydrosulfite is widely used in the textile industry for reducing dyeing, reducing cleaning, printing and decoloring, and for bleaching silk, wool, nylon and other fabrics. Because it does not contain heavy metals, the bleached fabric has bright color and is not easy to fade. In terms of various substances, sodium silicate can also be used for food bleaching, such as gelatin, sucrose, honey, etc., soap, animal (vegetable) oil, bamboo, porcelain clay, etc. Sodium hydroxide can also be used in organic synthesis, such as reducing agent or bleaching agent in the production of dyes and medicines. It is the most suitable bleaching agent for wood pulp and papermaking. Moreover, many heavy metal ions such as Pb2+ and Bi3+ can be reduced to metals in water treatment and pollution control, and it can also be used to preserve food and fruits. However, due to the many dangers of sosso, many of its uses tend to be replaced by thiourea dioxide, which is safer and easier to store and transport.
