Hypophosphorous acid waa wax yareeya.monobasic acid xoog leh.Xalka aqueous waa aashito ah oo si tartiib tartiib ah u oksaydheyn karaa hawada heerkulka qolka.Xidhiidhka lala yeesho wakiilka samaynta pore ee H waxay keeni kartaa gubasho.Gubashada ay sabab u tahay falcelinta daran ee oksidayaasha.Gaaska Fosphine, kaas oo aad u sun ah sababtoo ah burburka kulaylka sare, xitaa wuu qarxaa.Daxaluq.Hypophosphorous acid ayaa inta badan lagu daraa cabitaano qabow sababtoo ah lama nuugo.Markaa khatartu way yar tahay, laakiin Hypophosphorous acid oo leh feejignaan aad u xoog badan waxay dhaawici doontaa mareenka caloosha iyo mindhicirka.Kuleylinta aashitada adag ilaa 130-140 ℃ waxay keentaa kala qaybsanaan iyo kala jajabaan PH3 iyo H3PO4.

Hypophosphorous acid, oo sidoo kale loo yaqaan "hypophosphite", saliid aan midab lahayn ama crystals deliquescent, waa badeecad muhiim ah oo ka mid ah warshadaha kiimikada ee wanaagsan.Waxaa inta badan loo isticmaalaa sidii wakiilka yaraynta ee dahaadhka elektiroonigga ah si looga hortago midab-beelka xadhkaha phosphoric acid, iyo sidoo kale kicinta iyo qaboojiyaha falcelinta falcelinta, gaar ahaan soosaarka sare ee Sodium hypophosphite.Waxaa jira habab badan oo diyaarin ah, kuwaas oo hababka diyaarinta caadiga ah ee warshadaha ay yihiin habka resin beddelka ion iyo habka Electrodialysis.

Adeegsada

1. Hypophosphorous acid waxaa loo isticmaalaa sida hoos u dhigista walaxda dahaarka elektaroonigga ah;
2. Waxaa loo isticmaali karaa si looga hortago midab-beelka xabagta fosfooraska;
3. Waxa loo istcimaalaa sida kicinta esterification, qaboojiyaha;
4. Waxaa loo isticmaalaa in lagu soo saaro hypophosphite, cusbada sodium, cusbada manganese, cusbada birta ayaa guud ahaan loo isticmaalaa walxo nafaqo leh;
