Sodium Hypophosphite
CAS Number: #10039-56-2 (Monohydrate), 7681-53-0 (Andyrous)
Quality and Characteristic:
White crystal with no clumps, be able to absorb moisture and be soluted in water. It is exploded if mixed with oxidant over 200 degree centigrade. It will suddenly separate out hydrogen phosphorus. Molecular weight is 105.99.
Packing: In 25KG kraft paper bags inner coated with PE film, inner lined with PP bags.
Usage: Sodium Hypophosphite is often applied as reductant in non-electrical deposition of nickel (Nickel Chloride, buffers. ) It builds complexes with the nickel in the bath, improving the fineness of the surface after treatment.
Storage: Store in a cool, well-ventilated area. Keep away from ignition sources, heat and flame. Store in tightly closed container. Incompatibilities: Oxidants and food.
