Acid na Phosphorus， wani sinadari ne mara tsari wanda ke ɗauke da sinadarin H3PO3. Farin foda ne mai launin crystalline, wanda yake narkewa cikin ruwa da ethanol cikin sauƙi, kuma a hankali yana narkewa cikin iska zuwa orthophosphate. Phosphite acid ne na dibasic, acidity ɗinsa ya ɗan fi ƙarfi fiye da phosphoric acid, yana da ƙarfin rage ƙarfi, yana da sauƙin rage ions na azurfa (Ag+) zuwa ƙarfe na azurfa (Ag), yana iya rage sulfuric acid zuwa sulfur dioxide. Yana da ƙarfin hygroscopic da ɗanɗano, kuma yana da lalata.
