Title: Neutralisation of Hypophosphorus acid with sodium hydroxide
Post by: btzwong on July 08, 2010, 09:31:14 AM

H₃PO₂ + NaOH  :rarrow: NaH₂PO₂ + H₂0

Just wondering is the salt formed during the neutralisation of hypophosphorus acid with sodium hydroxide is sodium hypophosphate? Is there other products?

I think those are the only products.

It depends on how much NaOH is added.  If there is an excess of NaOH over H₃PO₂, then you'll see species like Na₂HPO₂ and Na₃PO₂.
