The chlorine in bleach is the same as the chlorine in drinking water and in a swimming pool. In fact, you can use chlorine bleach to treat a swimming pool or to treat drinking water. A gallon of regular bleach provides 1 part per million (PPM) of chlorine to 60,000 gallons (about 25...
3 Chlorine is in Group VII of the Periodic Table(a)Two isotopes of chlorine are chlorine-35 and chlorine-37(i)State why these two isotopes of chlorine have the same chemical properties.[2](ii) Complete the table to show the number of electrons, neutrons and protons in each atom and ion...

This study investigated the efficacy of sodium chloride (SC) and trichlorfon (T) against Dawestrema cycloancistrium and its physiological effects on Arapaima gigas. The efficacy of chlorine (C) as a prophylactic disinfectant was also evaluated. In vitro test with 15 treatments were: SC 4, 8,...
Here, we use cld as a biomarker for chlorite in microbial genomes to expand what is known about the biology of chlorine oxyanions and redox chemistry. This comparative genomics approach adopts only two assumptions: that microorganisms encoding Cld experienced chlorite, and that genetic proximity to ...

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)
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 ...
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 ...
