2【题目】阅读下列短文,写出有关反应的化学方程式Chlorine is manufactured by the electrolysis ofsodium chloride. It is a greenish-yellow,poisonous gas with a pungent smell. Chlorine issomewhat soluble in water, forming chlorinewater. Chlorine water contains dissolvedchlorine and hydrochloric and hypochloric...
chlorine- a common nonmetallic element belonging to the halogens; best known as a heavy yellow irritating toxic gas; used to purify water and as a bleaching agent and disinfectant; occurs naturally only as a salt (as in sea water)
awhen chlorine is added to water, part of it evaporates into the air, causing the familiar odor, and the rest is present in water in the following forms:chlorine, hypochlorous acid, hydrochloric acid, hypochlorous anion, and chloride. 当氯增加到水时,一部分的它蒸发入空气,导致熟悉的气味,并且...
Chlorine is abundant in cells and biomolecules, yet the biology of chlorine oxidation and reduction is poorly understood. Some bacteria encode the enzyme chlorite dismutase (Cld), which detoxifies chlorite (ClO2−) by converting it to chloride (Cl−) and molecular oxygen (O2). Cld is highly...
Plastic pollution—“a scourge on a planetary scale,” as French president Emmanuel Macron has put it—most affects those least able to deal with its consequences. Noting that the plastic industry generates upward of $700 billion a year in revenues, the UN Environment Programme also concluded...
Chlorine has an atomic number of 17 (Z = 17). Like all Group 17 (halogen) elements, atoms of chlorine can gain an electron to form an anion (negatively charged ion) with a charge of 1-. ... We say that that the chloride ion is isoelectronic withthe argon atom. ...
As such, it has the ability to dissolve and absorb molecules from a number of substances. These dissolved particles in a volume of water are the total dissolved solids (TDS) level. TDS has two forms, organic and inorganic. Understanding and calculating the total dissolved solids p...
That is so close that in reality, the chloride is more easily oxidized than the water is so chlorine gas forms at the anode and very little oxygen is formed (Due to the overvoltage). So what happens is that you get a solution of sodium hydroxide from the reduction of water at the ...
