Barium hypophosphite is an inorganic chemical compound, with the formula BaH4O4P2.
Contents
Properties
Chemical
Barium hypophosphite will react with concentrated sulfuric acid to yield concentrated hypophosphorous acid and barium sulfate.
Physical
Barium hypophosphite is a colorless solid, soluble in water.
Availability
Barium hypophosphite is sold by chemical suppliers.
Preparation
Can be prepared by neutralizing barium hydroxide with hypophosphorous acid.
- Ba(OH)2 + HO-P(O)H2 → BaH4O4P2 + 2 H2O
Alternatively, it can also be prepared by adding white phosphorus to an aq. suspension of barium hydroxide.[1]
Projects
- Make transition metal hypophosphites
Handling
Safety
Barium hypophosphite is harmful and should be handled with care.
Storage
In closed plastic or glass bottles, away from oxidizers.
Disposal
Addition of hydrogen peroxide to barium hypophosphite will give barium phosphate, which has low toxicity due to its poor solubility.
