Barium hypophosphite is an inorganic chemical compound, with the formula BaH4O4P2.

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.
