Copper nitrate: gwada yawa da kuma gwajin kwari halaye

Kalmar "nitrate" yana nufin mai gishiri sunadarai sanannun nitric acid, wanda qunshi wani barnatar da cajin kashi NO3. A mineralogy da aikin noma shi ne har yanzu sau da yawa sosai amfani da sauran nitrates nadi - "nitrate", amma a nan shi ne a hankali maye gurbinsu da sunan kimiyya mafi wajaba a kansa.

La'akari da muhimman hakkokin sinadaran Properties na nitrates, shi ne, na farko, lura cewa suna kafa ta maida martani nitric acid tare da oxides, salts da kuma, fiye da sau da yawa, tare da karafa. A dakin da zazzabi yanayi ma duk nitrates ne sosai resistant, amma a lokacin da zafin jiki yakan zuwa 200-6000 ° C, suka fara ya narke, a hankali saki a cikin aka gyara.

Af, abin da a kan abin da abubuwa decompose nitrates, za a iya hukunci a kan abin da wuri suna da, a cikin electrochemical jerin daga karfe danniya. A musamman, duk da nitrates, wadda ta bazuwar nuna nitrites da oxygen kwayoyin, dauke da karafa wanda suke zuwa hagu na magnesium (msl, lithium, barium, aluminum, cobalt). Wadanda nitrates, wanda decompose ta samar da nitrogen oxides da karfe, da oxygen a electrochemical jerin aka shirya a wani lokaci-lokaci daga magnesium zuwa tagulla.

Copper nitrate behaves a hanya ta musamman: da oxygen a lokacin da bazuwar ba saki, kuma an kafa bivalent jan oxide da nitrogen dioxide. Kuma, misali, wani bayani na azurfa nitrate decompose a zazzabi da "kawai" 1700 ° C, Highlights ba kawai tsarki oxygen zuwa tetravalent nitrogen oxide, amma kuma kai tsaye azurfa kwayoyin.

Har ila yau, ya kamata a lura shi ne cewa da cikakken duk nitrate ne mai karfi da oxidant, kuma shi ne a wani m jihar. Amma a cikin bayani da suka rasa su oxidative Properties, iri dabam-dabam da shi daga wannan nitric acid.

Tuni a zamanin da mutane sun lura da cewa nitric acid gishiri da kuma, fiye da dukan, nitrates ne m gargajiya, wanda suna da ikon mayar da ƙasa haihuwa. Daga baya, wani babban ɓangare na nitrate aka yi amfani don ƙirƙirar nakiyoyi da kwayoyi.

A musamman rawar da mulkin daga nitrates da tagulla nitrate.

Copper nitrate (Cu (NO3) 2) wakiltar wani hadadden inorganic abu a cikin tsari da kuma sinadaran Properties alaka da jan salts da kuma nitric acid. The jiki Properties na jan nitrate ne mai ɗamfarar da crystal raga, da narkewa a cikin ruwa da kuma wasu mafita (msl, ethanol, ruwa ammonia, ethyl acetate). A lokaci guda kamar yadda da dama sauran salts na nitric acid, jan nitrate garwaya da danshi ta samar da wata takamaiman crystal duhu blue color, wanda Ya shimfiɗa a cikin iska da wani babban zumunta zafi.

Chemical Properties na nitrate da alaka, a daya hannun, cewa matauni taro na jan karfe - m, kuma daidai da 64 g / mol, da sauran - da da ikon da tagulla nitrate zuwa sha danshi, game da shi, musanyãwa da sunan (nitrate - trihydrate - hexahydrate), da dũkiyõyinsu. Saboda haka, misali, anhydrous jan hydrate ya bazu a zazzabi na 1700 ° C da trihydrate - riga a 1200 ° C.

Matauni taro na jan karfe ne kuma muhimmanci cewa babba Hanyar samun anhydrous jan nitrate ne da kira na jan karfe kwayoyin da tetravalent oxide da tagulla. Ya kamata a haifa tuna cewa jan nitrate ne a wajen mai guba abu, don haka ta samarwa da kuma ajiya ya zama daidai da abin da bukatu na aminci da dokokinta. A musamman, wajibi ne a ji tsoro cewa wannan abu bai samu zuwa mucous membranes ko fata na da wani mutum, kamar yadda a cikin wannan hali, akwai hangula, wanda zai iya sa cututtuka daban-daban.

Af, kusan duk nitrates sa wadannan ko wasu raunuka da fata. Alal misali, wannan azurfa nitrate bayani a lamba tare da 'yan Adam fata sa bayyanar baki spots, kuma idan ta rike dogon isa, zai iya haifar da kuna.
