Aluminum hydroxide

Harshen aluminum hydroxide abu ne kamar haka. A matsayinka na mulkin, wannan abu abu ne mai fari, gelatinous, ko da yake akwai bambancin kasancewa a cikin crystalline ko amorphous jihar. Alal misali, a cikin samfurin dried yana rufewa cikin lu'ulu'u na lu'ulu'u, wanda ba ya rushe ko dai acids ko a alkalis.

Aluminum hydroxide kuma za a iya wakilta ta mai kyau-grained farin foda. Gabatarwar ruwan hoda da launin toka yana da karɓa.

Ma'anar da ake amfani da su a cikin gidan shi ne Al (OH) 3. A fili na alumina da ruwa ya samar da wata hydroxide na aluminum, sinadaran Properties wanda ake ma sun fi mayar da m da abubuwa a cikin abun da ke ciki. An shirya wannan fili ta hanyar yin amfani da gishiri na aluminum da kuma juyawa alkali, yayin da suke guje wa ƙarancin. Sakamakon aluminum hydroxide da aka samar a cikin wannan aikin zai iya amsawa tare da acid.

Aluminum hydroxide ya haɗu da wani bayani mai ruwa na rubidium hydroxide, wani allurar wannan abu, cesium hydroxide, cesium carbonate. A duk lokuta, an sake ruwa.

Aluminum hydroxide yana da wani kwayoyin nauyi daidai 78,00, kusan insoluble a ruwa. Yawancin abu shine 3.97 g / cm3. Kasancewa da amphoteric, aluminum hydroxide ya haɗu da acid, tare da sakamakon cewa halayen samar da matsakaici salts da saki ruwa. Bayan shigar da halayen tare da alkalis, hadadden salts - hydroxoaluminates, alal misali, K [Al (OH) 4 (H2O) 2] ya bayyana. Meta-aluminates an kafa idan an saka aluminum hydroxide tare da anhydrous alkalis.

Kamar dukan amphoteric abubuwa, acidic da asali Properties na biyu aluminum hydroxide nuna ta dauki tare da karfi acid da kuma alkalis. A cikin wadannan halayen, yayin da aka rushe hydroxide a cikin acid, ana kwance ions na hydroxide kanta, kuma a cikin amsa tare da alkali, an raba wutar hydrogen. Don ganin wannan, shi ne zai yiwu, misali, da za su gudanar da dauki, wanda ya shafi aluminum hydroxide, sodium hydroxide. Don gudanar da shi, wajibi ne a cika karamin sawdust a cikin gwajin gwaji kuma a zuba karamin adadin sodium hydroxide, ba fiye da 3 milliliters ba. Dole a rufe kullu tare da mai tsalle, kuma fara jinkirtawa. Bayan haka, gyaran tube zuwa wani tafiya, dole ne a tara gasasshiyar mai tsabta a cikin wani bututu, bayan an saka shi a kan tsalle-tsalle. Bayan kimanin minti daya, sai a cire gilashin gwajin daga capillary kuma a kawo shi cikin harshen wuta. Idan an samo hydrogen mai tsabta a cikin gwajin gwajin, konewa zai ci gaba da sauƙi, a cikin wannan hali, idan iska ta shiga ciki, auduga zai faru.

Aluminum hydroxide an samu a cikin dakunan gwaje-gwaje a hanyoyi da dama:

- ta hanyar amsawar hulɗar aluminum salts da alkaline mafita;

- hanyar da bazuwar aluminum nitride a ƙarƙashin rinjayar ruwa;

- ta hanyar wucewa ta carbon ta hanyar ginin gine-gine na musamman wanda ya ƙunshi Al (OH) 4;

- aikin hydrate na ammoniya a kan aluminum salts.

Samar da aikin masana'antu da aikin bauxite. Ana amfani da fasaha na tasiri akan aluminate mafita ta carbonates.

Aluminum hydroxide ana amfani da shi wajen yi da ma'adinai na ma'adinai, cryolite, da dama likita da kuma pharmacological shirye-shirye. A cikin samar da sinadaran, ana amfani da abu don samar da furotin da sukari da sulfur dioxide. Hanyoyin da ba za a iya bawa ba a cikin samar da takarda, robobi, takarda da yawa.

Amfani da magani yana haifar da sakamako mai kyau na kwayoyi dauke da wannan kashi a cikin maganin cututtuka na ciki, ƙara yawan ƙwayar jiki, cututtuka na ulcer.

Lokacin da ake sarrafa abu, ya kamata ka yi hankali kada ka shayar da shi, yayin da suke haifar da mummunan lalacewar huhu. Yin kasancewa mai laushi, yana da haɗari a manyan allurai. Lokacin da lalacewa ke haifar da aluminosis.

Abubuwan da kanta kanta ba shi da lafiya, tun da yake ba ya amsawa tare da oxidants.
