Acidic oxides: Brief bayanin kungiyar

Acidic oxides - a wajen babban rukuni na hadaddun abubuwa da amsa tare da alkalis. Lokacin da wannan ya auku, irin gishiri samuwar. Amma tare da acid, ba su mu'amala.

Acidic oxides kafa yafi nonmetals. Alal misali, wannan kungiya na iya hada sulfur, phosphorus da chlorine. Bugu da ƙari kuma, abubuwa da irin wannan Properties za a iya kafa daga abin da ake kira gwamnatin rikon kwarya abubuwa da ciwon valence na daga biyar zuwa bakwai.

Acidic oxides ta dauki tare da ruwa zai iya samar da acid. Kowane inorganic acid ne daidai oxide. Alal misali, sulfur oxides samar da wata sulphate da sulphite acid da phosphorus - ortho da metaphosphate acid.

Acidic oxides da kuma hanyoyin domin su shiri

Akwai da dama na asali hanyoyin domin samar da oxides da acid Properties.

Mafi na kowa Hanyar ne hadawan abu da iskar shaka na nonmetal kwayoyin halitta da oxygen. Alal misali, sa'ad da martani tare da phosphorous oxygenic samu phosphorus oxide. Hakika, wannan hanya ne ba ko da yaushe zai yiwu.

Wani fairly na kowa dauki - abin da ake kira da harbe-harben oxygens sulfides. Bugu da ari, oxides da ta shirya da dauki na wani salts da acid.

Wani lokaci a yi amfani da dakunan gwaje-gwaje da kuma wani dan kadan daban-daban dabara. A lokacin da dauki na m acid cinyewa ruwa - dehydration tsari ya auku. Ba zato ba tsammani, shi ne saboda haka aka sani acidic oxides karkashin wani sunan - acid anhydrides.

Chemical Properties na acidic oxides

Kamar yadda aka ambata riga, da anhydrides za a iya mayar da martani tare da asali oxides ko Alkali. A sakamakon irin wannan dauki samar da m acid gishiri, kamar yadda ta dauki tare da wani tushe da kuma har yanzu ruwa. Wannan tsari characterizes asali Properties na acidic oxides. Bugu da ƙari, anhydrides ba su amsa tare da acid.

Wani dukiya daga cikin wadannan abubuwa - shi ne ikon amsa tare da amphoteric sansanonin da oxides. A sakamakon irin wannan tsari kuma samar salts.

Bugu da kari, wasu anhydrides amsa tare da ruwa. A sakamakon wannan tsari, da samuwar na m acid. Ta haka ne yake samu a cikin dakin gwaje-gwaje, misali, sulfuric acid.

Mafi na kowa anhydrides: taƙaitaccen bayanin

Mafi na kowa da kuma sanannun acidic oxide da aka dauke su carbon dioxide. Wannan abu kullum ne a colorless kuma odorless gas, amma tare da raunana m iyawa.

Ba zato ba tsammani, a karkashin yanayi matsa lamba na carbon dioxide iya zama ko dai a gaseous ko a m siffar (bushe kankara). Domin maida da carbon dioxide a cikin wani ruwa, shi wajibi ne don kara matsin lamba. Wannan dukiyar da ake amfani da ajiya na abubuwa.

Carbon dioxide ne a greenhouse kungiyar, saboda jefarwa ƙasa garwaya da infrared haskoki rike zafi a cikin yanayi. Duk da haka, wannan abu ne da muhimmanci sosai ga rayayyun kwayoyin halitta. Carbon dioxide dauke a cikin yanayi na duniya tamu. Bugu da kari, shi ne amfani da tsire-tsire a photosynthesis.

Sulfur trioxide, ko sulfur trioxide - wani wakilin wannan kungiya da abubuwa. Karkashin al'ada yanayi, shi ne wani colorless, sosai maras tabbas ruwa tare da wani m, gagarumin wari. Wannan oxide da matukar muhimmanci a cikin sinadaran masana'antu, saboda girma a cikinta nuna sulfuric acid.

Silica - quite wani sananne abu da yake a cikin al'ada jihar ne crystal. Af, da yashi shi ne daidai domin wannan connection. Silicon oxide lokacin tsanani m ya narke da solidify. Wannan dukiyar da ake amfani a yi na gilashi. Bugu da ƙari, abu ma bai gudanar da wutar lantarki a halin yanzu, don haka ta yi amfani da matsayin dielectric.
