Ko te waikawa Hypophosphorous he kaihoko whakaheke.Te waikawa monobasic kaha.He waikawa te wairewa wai, a ka taea te whakapouri i te hau i te pāmahana rūma.Ko te whakapā atu ki te māngai hanga H pore ka taea te wera.Te wera na te kaha o te tauhohenga me nga waikura.Ko te hau Phosphine, he tino paitini na te nui o te waiariki, ka pahū.Haehae.Ka taapirihia te waikawa hypophosphorous ki nga inu whakamatao na te mea karekau e ngongo.Na he iti te kino, engari ko te waikawa Hypophosphorous me te tino kaha o te kukū ka pa ki te kopa gastrointestinal.Ko te whakamahana i te waikawa totoka ki te 130-140 ℃ ka puta te koretake me te pirau ki te PH3 me te H3PO4.
Ko te waikawa Hypophosphorous, e mohiotia ana ko "hypophosphite", he karaehe hinuhinu kore he tae, he karaehe ngawari ranei, he hua nui o te umanga matū pai.Kei te nuinga whakamahia te reira rite te māngai whakaiti mo te whakakikorua electroless ki te ārai discoloration o phosphoric kapia waikawa, me rite te whakakōkī me te refrigerant mo te tauhohenga esterification, rawa mo te hanga o te High-pure Sodium hypophosphite.He maha nga tikanga whakarite, kei roto ko nga tikanga whakareri noa i roto i te umanga ko te tikanga kapia whakawhiti katote me te tikanga Electrodialysis.
