Topics related to "carbon"

carbonate
carbonate , chemical compound containing the carbonate radical or ion , CO 3-2 . Most familiar carbonates are salts that are formed by reacting an inorganic base (e.g., a metal hydroxide ) with carbonic acid . Normal carbonates are formed when equivalent amounts of acid and base react; bicarb... Read more

carbonic acid
carbonic acid H 2 CO 3 , a weak dibasic acid (see acids and bases ) formed when carbon dioxide dissolves in water; it exists only in solution. Carbonic acid forms carbonate and bicarbonate (or acid carbonate) salts (see carbonate ) by reaction with bases. It contributes to the sharp taste of ca... Read more
calcium carbonate
calcium carbonate CaCO 3 , white chemical compound that is the most common nonsiliceous mineral. It occurs in two crystal forms: calcite, which is hexagonal, and aragonite, which is rhombohedral. Calcium carbonate is largely insoluble in water but is quite soluble in water containing dissolved carb... Read more
carbon dioxide
carbon dioxide chemical compound, CO 2 , a colorless, odorless, tasteless gas that is about one and one-half times as dense as air under ordinary conditions of temperature and pressure. It does not burn, and under normal conditions it is stable, inert and nontoxic. It will however support combustio... Read more

carbon tetrachloride
carbon tetrachloride or tetrachloromethane , CCl 4 , colorless, poisonous, liquid organic compound that boils at 76.8°C. It is toxic when absorbed through the skin or when inhaled. It reacts at high temperatures to form the poisonous gas phosgene. Carbon tetrachloride is used in the producti... Read more
