Nitrogen da takin mai magani. ammonium nitrate

Ammonium nitrate ne kunshe a wani rukuni daga cikin mafi muhimmanci nitrogenous takin. Nitrogen aikin muhimmiyar rawa a shuka rayuwa. Wannan abu ne kunshe a cikin abun da ke ciki na chlorophyll, wanda shi ne wani Mai karɓar gina jiki da kuma hasken rana, wanda wajibi ne domin gina kwayar halitta mai rai.

Tsire-tsire suna iya cinye kawai mamaye nitrogen a cikin nau'i na amides, ammonium salts, nitrates. A gwada da kananan adadin kayan da aka kafa ta aiki da ƙasa kwayoyin. Ya kamata a lura da cewa zamani noma ba zai iya zama ba tare da ƙarin gabatarwar taki nitrogen kungiyar, wanda yake fãra daga masana'antu nauyin yanayi nitrogen. Gaurayawan kunshe a wannan category ne daban-daban daga juna a cikin wani nau'i na fili lokaci jiha (ruwa ko m). Asirce physiologically alkaline da acidic takin.

Ammonium nitrate, wanda dabara NH ₄ NO _3, shi ne wani fari crystalline abu, wanda qunshi talatin da biyar bisa dari na nitrogen a nitrate da ammonium form. Dukansu wadannan siffofin suna quite sauƙi tunawa da shuke-shuke. A granular ammonium nitrate da ake amfani a manyan yawa kafin shuka ayyuka da kuma yadda saman miya. The karami adadin da ake amfani a yi na bama-bamai.

Ammonium nitrate iya zama daban-daban. Nau'in A da B, misali, ana amfani da masana'antu dalilai a fashewar garwayayye (ammonal, da na Ammonawa).

Domin samar da taki amfani ammonia da nitric acid. A kwayoyin nauyi na da samu fili 80.043 amu Pure ammonium nitrate ƙunshi sittin cikin dari oxygen, hydrogen biyar bisa dari da talatin da biyar bisa dari nitrogen (babu kasa da talatin da hudu bisa dari a fasaha samfurin nitrogen sulusi da murabba'i).

Dangane da yawan zafin jiki, akwai biyar crystal gyare-gyare na wani abu. All ne thermodynamically barga a yanayi matsa lamba. Ga kowane canji na da takamaiman zazzabi yankin da kuma a polymorphic mika mulki unsa canza crystal tsarin, da sha ko saki zafi, ba zato canje-canje a cikin takamaiman girma, entropy, zafi iya aiki, da kuma sauransu. Irin canje suna dauke enantiotropically - reversible.

Ammonium nitrate ne oxidizing wakili da yake iya goyon bayan konewa. A cikin akwati inda thermal bazuwar kayayyakin ba su iya yardar kaina cire, da abu zai iya fashe (fashe) a karkashin wani yanayi.

Lokacin da fallasa su dagagge zafin jiki (ɗari biyu da goma - ɗari da ashirin digiri) a cikin rufaffiyar sarari, ammonia accumulates, da maida hankali nitric acid da aka saukar da. A wannan batun, akwai wani gagarumin karu a cikin bazuwar dauki. Thermal bazuwar kusan ba ya daina. Lokacin da fallasa su a mafi yawan zafin jiki, da mafi m hadawan abu da iskar shaka na ammonia, da dauki da aka tara abu fara gudãna daga tare da babba hanzari. Yana kuma iya fararwa wani fashewa.
