Hypophosphorous acid inoderedza mumiririri.Yakasimba monobasic acid.Iyo aqueous solution ine acidic uye inogona zvishoma nezvishoma oxidize mumhepo pakamuri tembiricha.Kubata neH pore kugadzira agent kunogona kukonzera kupisa.Kupisa nekuda kwekunyanya kuita nemaoxidants.Phosphine gasi, iro rine muchetura zvakanyanya nekuda kwekuora kwakanyanya kwekupisa, kunyange kuputika.Corrosive.Hypophosphorous acid inowanzowedzerwa kune zvinwiwa zvinotonhorera nokuti haina kubatwa.Saka njodzi idiki, asi iyo Hypophosphorous asidhi ine yakanyanya kusimba yekumisikidza inokuvadza gastrointestinal turakiti.Kupisa iyo asidhi yakasimba kusvika pa130-140 ℃ inokonzeresa kusaenzana uye kuparara kuita PH3 neH3PO4.

Hypophosphorous acid, inozivikanwawo se "hypophosphite", isina ruvara ine mafuta kana deliquescent crystal, chigadzirwa chakakosha cheindasitiri yemakemikari yakanaka.Inonyanya kushandiswa sechinhu chinodzikisira che electroless plating kudzivirira kushanduka kwephosphoric acid resin, pamwe chete secatalyst uye refrigerant ye esterification reaction, kunyanya pakugadzirwa kwepamusoro-kuchena Sodium hypophosphite.Kune nzira dzakawanda dzekugadzirira, pakati padzo nzira dzakajairika dzekugadzirira muindasitiri ndeye ion exchange resin nzira uye Electrodialysis nzira.
