Fosfooraska Acid |7664-38-2
Sharaxaada Alaabta
Fosfooraska aashitada waxay ku jirtaa dareere aan Midab lahayn, hufan oo sharoobo leh ama crystalline rhombic;barta dhalaalkeedu waa 42.35 ℃ oo marka la kululeeyo ilaa 300℃ fosfooraska acid waxay noqon doontaa metaphosphoric acid;cufnaanta qaraabada waa 1.834 g/cm3; fosfooraska acid si fudud ayay ugu milmi kartaa biyaha waxayna ku xalisaa ethanol;Phosphate acid waxay ka xanaajin kartaa maqaarka bini'aadamka si ay u keento phlogosis oo ay burburiso arrinta jidhka bini'aadamka;Aashitada fosfooraska waxay muujinaysaa daxalka lagu kululeeyo weelasha dhoobada;Acid fosfooraska waxay leedahay hydroscopicity.
Fosfooraska Acid waxay isticmaashaa:
Fasalka Farsamada Fosfooraska Acid waxa loo isticmaali karaa in lagu soo saaro noocyo kala duwan oo ah Fosfat, dareerayaasha daawaynta elektrolytka ama dareeraha daawaynta kiimikaad, hoobiye refractory leh fosfooraska acid iyo inorganic acid.In warshadaha daahan fosfooraska acid waxaa loo isticmaalaa sida daahan daxalka-proof for biraha;Sida nidaamiyaha aashitada iyo wakiilka nafaqada ee heerka cuntada phosphoric acid waxaa laga yaabaa in lagu dabaqo dhadhanka, cuntada qasacadaysan iyo cabitaannada fudud iyo sidoo kale loo isticmaalo khamriga khamriga sida ilaha nafaqo ee khamiirka si looga hortago taranka bakteeriyada aan faa'iido lahayn.
Falanqaynta Kiimikada

Codsiga
Fosfooraska Aciddu waxa ay ka saartaa siigada meelaha birta ah Waxa loo isticmaalaa beddelaha miridhku iyada oo si toos ah ula xidhiidhinaya birta daxalaysan, ama qalabka birta iyo meelaha kale ee daxalaystay.Waxay waxtar u leedahay nadiifinta kaydadka macdanta, sibidhka nous smears iyo wasakhda biyaha adag.Waxaa loo isticmaalaa in lagu acidify cuntooyinka iyo cabitaannada sida koollada.Fosfooraska Acid waa qayb muhiim ah oo ka mid ah daawooyinka miiska laga iibsado si loola dagaallamo lallabada.Fosfooraska Acid waxaa lagu qasaa budada zinc waxayna sameysaa zinc phosphate, waxayna faa'iido u leedahay sibidhka ilkaha ee ku meel gaarka ah.Dhaqdhaqaaqa lafaha, zinc waxaa loo isticmaalaa sidii xal etching ah si ay uga caawiso nadiifinta iyo qallafsanaanta dusha sare ee ilkaha.Bacriminta falcelinta loo isticmaalo ciidda agagaarka aashitada granule ayaa la soo saaray taasoo wanaajisa ka faa'iidaysiga fosfooraska codsatay oo laga heli karo rhizosphere.Sababtoo ah waxa ku jira nitrogen (oo hadda ku jira sida ammonia), waxay u fiican tahay dalagyada u baahan nafaqooyinkan marxaladda hore.
