The formula for aluminum chloride is correctly written as: AlCl3 The formula for aluminum chloride is correctly written as Weegy: The valence of aluminum is +3 and the valence of chlorine is -1. User: The valence of aluminum is +3, and the valence of chlorine is -1. Free hydrochloric acid is present in the stomach.Weegy: With regard to the pH scale, a solution with a pH: close to 14 is considered a strong base. It is found in evaporite minerals such as chlorapatite and sodalite. Other chlorine-containing minerals are sylvite ( potassium chloride ), bischofite (MgCl 2 ∙6H 2O), carnallite (KCl∙MgCl 2 ∙6H 2O), and kainite (KCl∙MgSO 4 ∙3H 2O). Small quantities of sodium chloride are present in blood and in milk. Certain landlocked seas, such as the Caspian Sea, the Dead Sea, and the Great Salt Lake of Utah, contain up to 33 percent dissolved salt. Sodium chloride is also present in seawater, which has an average concentration of about 2 percent of that salt. The most common compound of chlorine is sodium chloride, which is found in nature as crystalline rock salt, often discoloured by impurities. Natural chlorine is a mixture of two stable isotopes: chlorine-35 (75.53 percent) and chlorine-37 (24.47 percent). It constitutes 0.017 percent of Earth’s crust. Occurrence and distributionĪpart from very small amounts of free chlorine (Cl) in volcanic gases, chlorine is usually found only in the form of chemical compounds. The true nature of the gas as an element was recognized in 1810 by English chemist Humphry Davy, who later named it chlorine (from the Greek chloros, meaning “yellowish green”) and provided an explanation for its bleaching action. In 1774 the Swedish chemist Carl Wilhelm Scheele treated powdered black oxide of manganese with hydrochloric acid and obtained a greenish-yellowish gas, which he failed to recognize as an element. Later he obtained the same product, now known to be hydrochloric acid, by heating salt with sulfuric acid. In 1648 the German chemist Johann Rudolf Glauber obtained a strong acid, which he called spirit of salt, by heating moist salt in a charcoal furnace and condensing the fumes in a receiver. In Roman times, soldiers were partially paid in salt ( salarium, the root of the modern word salary). It is the main constituent of the salts dissolved in seawater, from which it was obtained in ancient Egypt by evaporation. Rock salt (common salt, or sodium chloride) has been known for several thousand years.
