  گروهی از مواد سمی هستند که در اثر حرارت بصورت گازمی باشد    گازهای سمی  مسمومیت هایی که توسط این گازها ایجاد می شود،درصورت عدم درمان بموقع ،منجر به مرگ فرد مسموم خواهند شد . گازهای سمی چون از راه تنفس وارد بدن می شوند، بسهولت وارد جریان خون می شوند و به فاصله چند ثانیه به مراکز عصبی   می رسند .  مهترین گاز های سمی :  مونوکسید کربن (CO) یکی ازخطرناکترین گازهای سمی مونوکسیدکربن است ،که گازی بی رنگ ، بی بو و بی طعم  می باشد . این گاز از احتراق ناقص زغال و مواد آلی تولید می شود . دی اکسیدکربن  (CO2) گازی است بی رنگ،بی بو، با طعم کمی سوزاننده این گاز درحقیقت سمی نیست و مقدارکم آن مراکز تنفسی راتحریک می کند . کلر کلر گازی است زرد مایل به سبز،در آب محلول است و بشدت مراکز تنفسی را تحریک می کند .   کلرور کربونیل  (COCl2) فوسژن گازی است بی رنگ با بوی نافذ و شبیه بوی علف خشک گازی است محرک و خفه کننده که سرفه ، ریزاشک و تنگی نفس ایجاد می کند.   اسید سولفیدریک  (H2S) گازی است بی رنگ با بوی ...

LITHIUM AND ITS COMPOUNDS

LITHIUM AND ITS COMPOUNDS Lithium (from Greek: λίθος, translate. lithos, lit. ‘stone’) is a chemical element with symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. Like all alkali metals, lithium is highly reactive and flammable, and is stored in mineral oil. When cut, it exhibits a metallic luster, but moist air corrodes it quickly to a dull silvery gray, then black tarnish. It never occurs freely in nature, but only in (usually ionic) compounds, such as pegmatitic minerals, which were once the main source of lithium. Due to its solubility as an ion, it is present in ocean water and is commonly obtained from brines.  Lithium metal is isolated electrolytically from a mixture of lithium chloride and potassium chloride. GENERAL DESCRIPTION OF LITHIUM AND ITS COMPOUNDS Lithium is a soft, the lightest, silver-white, highly reactive metallic element in Group 1 of periodic ta...
