HPA (Hypophosphite Acid 50%)

Moderately strong monoacid and a strong reducing agent,which could easily be oxidized in the air. When exposed to strong heat or oxidant,it will decompose into phosphine, phosphoric acid, phosphite acid and hydrogen. HPA should bekept in ventilated and dry place. Avoid high temperature and oxidants. Prevent spilling because of its strong causticity.AppearanceColorless transparent liquidH2PO250-52%Density1.200-1.265g/mlH3PO3≤0.5%Fe≤0.001%Cl-≤0.01%Chroma(APHA)≤30%
