what is the uses of chlorine How Chlorine Keeps Pools Safe for Summertime Fun? Most people probably wouldn’t want to go swimming in a giant, germ-filled petri dish. But without modern chemistry, that’s what swimming in pools could be like. Even a quick swim in unsanitized water could expose a person to illnesses such as diarrhea, swimmer’s ear and various types of skin infections, including athlete’s foot. What experts say about chemicals and pool safety: The U.S. Centers for Disease Control and Prevention (CDC) states that chlorine is added to water to kill germs. Chlorine and pH are the first line of defense against germs that can make swimmers sick, according to CDC.  Whether you choose chemical products or electrical devices to clean your pool or spa, you must maintain a certain amount of sanitizer to prevent disease-causing microorganisms from multiplying, according to Health Canada.  Belgian scientists also support pool disinfection, stating that chlorine is the best

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 table;
