Chlorine also makes a great stain remover, but not because of the chlorine itself. Natural stains (as well as dyes) produced by everything from mildew to grass come from chemical compounds called chromophores.
阅读下列短文,写出有关反应的化学方程式。Chlorine is manufactured by the electrolysis of sodium chloride. It is a greenish-yellow,poisonous gas with a pungent smell. Chlorine is somewhat soluble in water, forming chlorine water.Chlorine water contains dissolved chlorine and hydrochloric and hypochloric ...

The solution to this gassing problem is to eliminate the chloride ion contaminates. The most important step in reducing chloride contamination is the avoidance of potassium perchlorate (KClO 4 ) or any other chlorine-containing substances that can decompose to produce chloride ions in any thermal ...

PVC is made of carbon, hydrogen, and chlorine. As a result, it is a source of vinyl chloride monomer (VCM) and phthalates, which are considered carcinogenic materials. The ideal use for PVC is in the building materials and construction applications, like PVC pipes and electric cables, but ...
intake of sodium, you need to realize the quantity of salt you eat is related to the amount of sodium but is not the same. This is because salt contains both sodium and chlorine, so when salt dissociates into its ions, the mass is divided (not equally) between sodium and chlorine ions...
