stability

1. Stable at normal temperature and pressure.

 

2. Forbidden compound: strong oxidant. Soluble in water, slightly soluble in alcohol. It has strong reducibility under high temperature, which can make the dyed color disappear, so it is called hanging white block. In case of acid decomposition, decomposition at 120℃ produces formaldehyde, hydrogen sulfide and other toxic gases. Anhydrous lump is stable, but gradually breaks down in humid air. Aqueous solution begins to decompose above 60℃, and dilute solution decompose much faster than concentrated solution.

 

3. Aqueous solution is more stable below 50 ℃, decomposition into sulfite at high temperature, easy oxidation and delixing contact with air, soluble in water is more alkaline, more stable in neutral or alkaline solution, acidic medium is extremely unstable, reducing effect at high temperature, this product is more stable than insurance powder.
