Disodium hydrogen phosphite
This product is a reddish orthorhombic crystal. The performance is quite stable at normal temperature, and hydrogen and phosphine are released during heating to form orthophosphate or pyrophosphate. Mainly used as a reducing agent to reduce metal salts to the corresponding metals. The container remains tightly closed. Store in a dry, well-ventilated place.
