Hydroxide mkuwa

Mkuwa hydroxide pawiri (II) - ndi yowala buluu timibulu, amathanso ndi amorphous (anawombera) kapangidwe. Ndi insoluble m'madzi, adziwe wamba chitetezo kaundula. Mankhwala opangidwa ndi chinthu - Cu (o) ₂, ndi patsinde ofooka, omwe amagwiritsidwa akamagwira ntchito a m'munsi kwambiri salt zamkuwa.

The ntchito pawiri izi inafalitsidwa mu zosiyanasiyana za mankhwala ndi mafakitale kupanga. Choncho, hydroxide mkuwa ntchito ngati pigmenting chigawo magalasi, mankhwala ceramic ntchito luso ndi miyala yamtengo wapatali, glazes. Mtundu katundu wa mankhwala akhala bwino ntchito kupanga utoto mkulu zosagwira, amene ntchito ntchito pansi zombo ngakhale sitima zankhondo, monga mankhwala kumathandiza fouling mbali m'madzi a zombo ndere ndi zinthu zina madzi kusokoneza ziwiya zitsulo.

chiyembekezo chachikulu ntchito chinthu mafomu ano magetsi ndi zamagetsi. Pano, zikhoza kukhala kofunika kwambiri chigawo chimodzi cha njira zamakono mkulu-kutentha superconductors kupanga. Komanso, ntchito zomangamanga magetsi kale anayesedwa pa mchitidwe zasayansi.

Makamaka mankhwala opanga hydroxide mkuwa chimagwiritsidwa ntchito monga kuthandiza munthu zochita mankhwala. Komanso n'zothekanso kuti mwachindunji ndi m'minda ngati ntchito ya thunthu, monga yokonza chakudya kwa ziweto, ulimi wa sukulu zosiyanasiyana kupanga, makamaka chokongoletsedwa (akuda) kupanga.

Ngakhale kuti chitetezo gulu pawiri si mankhwala kwambiri poizoni komanso woopsa, kugwira nawo n'kofunika kukwaniritsa ena mosamala zofunika. Zimenezi zikugwira koposa zonse kutsatira zinthu kusunga kanthu ndi kupewa izo kuchokera kuwataya milandu panja. Ngati zimenezi zachitika, muyenera yomweyo kugwiritsa kudzipatula danga ndowe ndi hydroxide nazo ku mtunda otetezeka.

Malinga ndi chilinganizo, hydroxide mkuwa - ndi pawiri zamchere. Choncho, onse amene alipo ndi tsogolo mabaibulo ntchito zimene mukuphunzirazo, izo amayamba ndi katundu zamchere.

Pamaso kuyankha funso mmene kutenga hydroxide mkuwa, ayenera kupanga malo amene pali zingapo zimene mungachite zimenezi.

Taonani ena mwa anthu ambiri.

Cupric hydroxide akhoza kulandira kuchokera sulphate ake. mankhwala mosavuta sungunuka m'madzi, woyera ufa ndi eg crystalline. mankhwala chilinganizo ake - CuSO₄. Ngati mankhwala otchedwa mkuwa sulphate kusungunuka m'madzi akhoza kuwapeza pa kudziwika sulphate mkuwa. Ndiye, ngati njira Chinawonjezeka ndi soda, zimene zidzachitika amene aime ndi Cu (o) ₂ mu mawonekedwe a precipitate a mtundu buluu.

Hydroxide mukhonza kuwapeza nitrate mkuwa (II), chimene chiri crystalline mankhwala opanda mtundu, ndi mankhwala chilinganizo Cu (NO₃) ₂. Ngati zimene ikuchitika kupeza hydroxide ndi, m'pofunika NaOH njira Chinawonjezeka mkuwa nitrate (II). Zimene chifukwa precipitate a mtundu buluu ndi kufunika mkuwa hydroxide.

A njira wamba yodalirika chinthu ndi ntchito imeneyi mankhwala enaake mkuwa (II), amene ali ndi mankhwala chilinganizo CuCl₂. Pakuti hydroxide ayenera chikasu ufa umene uli mkuwa mankhwala enaake kusungunuka wina kuchuluka kwa soda. Pa maganizo timibulu chikasu kutha, ndipo m'malo imagwera onse chomwecho zofunikira ife precipitate buluu hue - Cu (o) ₂.
