A na-eji Potassium chloride (KCl) na nkwadebe ọgwụ yana dịka mgbakwunye nri na reagent kemịkal.Ọ ga-ekwe omume ibelata sodium na nri gị site n'ịgbanwe potassium chloride maka nnu tebụl (sodium chloride), nke nwere ike ịdị mma karị.A na-ejikwa potassium chloride a wụrụ awụ mee ihe na mmepụta electrolytic nke potassium dara.A na-ahụkwa KCl na mmiri mmiri mmiri brine ma nwee ike wepụ ya na carnallite ịnweta.
Potassium chloride bụ ihe na-edozi ahụ, mgbakwụnye nri, na onye na-ahụ maka gelling nke dị dị ka kristal ma ọ bụ ntụ ntụ.o nwere ihe solubility nke 1 g na 2.8 ml mmiri na 25 Celsius C na 1 g na 1.8 ml nke mmiri esi.hydrochloric acid, na sodium chloride na magnesium chloride na-ebelata solubility ya na mmiri.a na-eji ya eme ihe dị ka ihe mgbakwunye nnu na mgbakwunye ịnweta.ọ nwere nhọrọ eji eme jelii na-atọ ụtọ ma na-echekwa ya.a na-eji ya dị ka isi iyi potassium maka ụfọdụ ụdị carrageenan gels.a na-eji ya dochie sodium chloride na nri sodium dị ala.
Potassium chloride bụ reagent ụlọ nyocha eji eme ka viscosity ngwaahịa dị na nkwadebe ịchọ mma na ọgwụ.
Potassium chloride (KCl), nke a na-akpọkarị muriate nke potash, bụ ebe a na-esi enweta potash (K2O), na ihe dị ka pasentị 95 nke mmepụta potash ụwa.Ihe fọrọ nke nta ka ọ bụrụ ihe niile (90%) a na-amịpụta potash a na-ere ahịa site na isi mmalite nke nnu potassium na-apụta n'ime akwa akwa dị mkpa n'ime nnukwu efere nnu mere site na ikuku nke oke osimiri oge ochie.Ọdọ mmiri nnu nke oge a na brines sitere n'okike na-anọchi anya ihe dịka pasenti 10 nke mkpokọta potassium nwere ike nwetaghachi.A na-esote mmịpụta site na igwe igwe, ịsa ahụ, nyocha, flotation, crystallization, nnụcha na ihicha.
A na-eji ihe karịrị 90% nke mkpokọta KCl maka mmepụta fatịlaịza.Mmepụta potassium hydroxide na-akpata ihe karịrị 90% nke anaghị fatịlaịza ma ọ bụ ụlọ ọrụ mmepụta ihe nke KCl.A na-ejikwa KOH na-emepụta ụfọdụ fatịlaịza mmiri mmiri na ọkwa ugbo.ojiji nke KCl gụnyere:
Potassium chloride (KCl) bụ nnu inorganic nke a na-eji eme fatịlaịza, ebe ọ bụ na uto nke ọtụtụ osisi na-ejedebe site na oriri potassium ha.Potassium dị n'ime osisi dị mkpa maka usoro osmotic na ionic, na-arụ ọrụ dị mkpa na homeostasis mmiri ma nwee njikọ chiri anya na usoro ndị metụtara njikọ protein.
