Description about chlorine Chlorine is a chemical element with symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature. Discovered in 1774 at Sweden by Carl Wilhelm Scheele, who mistakenly thought it contained oxygen. Chlorine was given its ...
Disinfection of potable water is the specialized treatment for destruction or removal of organisms capable of causing disease. Disinfectants widely used in water treatment are oxidizing agents such as chlorine. Being a strong oxidant chlorine will react with the oxidizable materials present in water before it has a chance to act as a disinfectant. Chlorine in water: Chlorine has been widely used in disinfecting water ...

How do you tell Polar from Nonpolar?? • From the IMF unit we learned. • If it’s dispersion (diatomic, noble gas, pure hydrocarbon, small symmetrical) it’s nonpolar • If it’s not it’s polar Polar Bond (Asymmetric) • Polar – has poles –Meaning ends are different –Polar bond: one end more electrons than other end • So there is a ...
