Azot d\u00fcnya etraf\u0131ndaki atmosferde oksijen ile kar\u0131\u015f\u0131m halinde bulunan renksiz gazd\u0131r. Atmosferin hacim olarak % 78.09\u2019u azot, % 20.95’i oksijendir. Kimyada (N) sembol\u00fc ile g\u00f6sterilir. Serbest halde bulunan azot, iki atomlu molek\u00fcller halinde bulunur. Bu y\u00fczden kimya reaksiyon denklemlerinde azot, N2 halinde yaz\u0131l\u0131r.<\/p>\n
Azot gaz\u0131 ile ilgili ilk \u00e7al\u0131\u015fma 1772 y\u0131l\u0131nda Priestley<\/strong> taraf\u0131ndan yap\u0131ld\u0131.\u00a0Priestley ilk defa havan\u0131n yanmayan k\u0131sm\u0131n\u0131n oldu\u011funu, ayn\u0131 y\u0131l i\u00e7inde Scheele<\/strong> havan\u0131n azot ve oksijen kar\u0131\u015f\u0131m\u0131 oldu\u011funu buldu. Azot’a ismini ise ilk defa Lavosier<\/strong> verdi.<\/p>\n Azot en \u00e7ok amonyak yapmada, az miktarda azotlu kire\u00e7 denilen kalsiyum siyanamid yap\u0131m\u0131nda kullan\u0131l\u0131r. Kimyasal reaksiyonlarda inert atmosfer olarak, s\u0131v\u0131 azot ise, s\u00fcper so\u011futmada kullan\u0131l\u0131r. Hava azotundan elde edilen amonyak, azotdioksit ve kire\u00e7li azot, g\u00fcbre olarak kullan\u0131l\u0131r. Azot bile\u015fiklerinden faydalanarak harp m\u00fchimmat\u0131 (patlay\u0131c\u0131 maddeler) yap\u0131l\u0131r. Genellikle bitkiler N2 molek\u00fcl\u00fc halindeki azotla bir \u015fey yapamazlar. Yani kendi b\u00fcnyelerine do\u011frudan al\u0131p hazmedemezler. Bitki, b\u00fcnyesindeki proteini in\u015fa edebilmek i\u00e7in laz\u0131m olan azotu topraktaki azot bile\u015fiklerinden al\u0131r.<\/p>\n Do\u011fal ve suni g\u00fcbreler bitkilere azot vermektedir. Baklagiller ve yoncalar elementel azotu kullan\u0131rlar. Fakat bu, bitkinin kendisi taraf\u0131ndan de\u011fil k\u00f6k\u00fcnde ya\u015fayan bakteriler taraf\u0131ndan yap\u0131l\u0131r. Bu bakteriler havadaki serbest azot molek\u00fcl\u00fcn\u00fc b\u00f6lme s\u0131rr\u0131n\u0131 bilirler ve havadan yapt\u0131klar\u0131 azot bile\u015fiklerini azot g\u0131das\u0131 olarak sunarlar. Bu sebeple baklagiller azot bak\u0131m\u0131ndan zengindir. Azot bile\u015fiklerince fakir olan tarlaya yonca ekildi\u011fi zaman topra\u011f\u0131n azot bak\u0131m\u0131ndan zenginle\u015fmesine sebep olur.<\/p>\n","protected":false},"excerpt":{"rendered":" Azot d\u00fcnya etraf\u0131ndaki atmosferde oksijen ile kar\u0131\u015f\u0131m halinde bulunan renksiz gazd\u0131r.
