Information

Main composition is calcium hypochlorite bleaching powder, calcium hypochlorite with hundreds of CO2 and water vapor in the air to generate hypochlorous acid and calcium carbonate (the reaction degree of bleaching powder is in fact the work), if you don't use will be photolysis (long dark also reacts to) produce the oxygen and hydrogen chloride gas (known as acid or salt), then failed.

Step 1: Ca(ClO)2+H2O+CO2===CaCO3↓+2HClO

Step 2:2HCLO===2HCl+O2↑ exactly this step deactivates the bleaching powder

Industrial bleaching powder is chlorine gas with Ca(OH)2?

(rewrites the equation)

2Ca(OH)2+2Cl2=CaCl2+Ca(ClO)2+2H2O

The bleach ingredient is

CaCl2· Ca (ClO) 2

1. Equation of bleaching powder's failure in air

Ca(ClO)2+CO2+H2O=CaCO3(sediment)+2HClO

2. Equation of excess CO2 into the bleach solution

Ca(ClO)2+2CO2+2H2O=Ca(HCO3)2+2HClO

3. Add dilute hydrochloric acid to the bleach solution

Ca(ClO)2+2HCl(diluent)=CaCl2+2HClO

After the test found that bleaching powder powder powder open storage, the content of the effective component of chlorine will change, under normal circumstances, effective loss of chlorine within 9 days should reach more than 50%, after 18 days, basically has no disinfection effect.

Does hypochlorous acid kill good bacteria?   Hypochlorous acid (HOCl) is the perfect weapon to fight germs. It hits hard against pathogens like Methicillin-Resistant Staphylococcus Aureus and Pseudomonas Aeroginosa. Yet this powerful weapon is 100 percent safe for humans, chemical free, non-toxic and all-natural. That’s an impressive combination. It has been used in the medical field for over a century. Before antibiotics were available, HOCl was used to irrigate and disinfect wounds in World War I.  It is now used in everyday settings including daycare centers, hospitals, and even produce sections in grocery stores. HOCl is a weak acid that occurs naturally in our body. Neutrophils are white blood cells that are the first to arrive on site when an invading pathogen is detected. Neutrophils will chase down and engulf the pathogen through phagocytosis. Upon contact, neutrophils release a burst of bactericidal chemicals including its most powerful oxidizing agent, HOCl. This kills the pathogen by tearing down the cell membranes and proteins.

Cancer-causing contaminants may be in your drinking water, according to a new study published in the journal Heliyon. Scientists at the Environmental Working Group (EWG) analyzed pollutants in tap water from 2010 to 2017. They found 22 carcinogenic contaminants — including arsenic, disinfection byproducts, and radioactive contaminants, such as uranium and radium — in drinking water nationwide, which researchers estimate could, over the course of an average lifetime (about 70 years), lead to 100,000 cases of cancer. The analysis found that water systems with the highest risk tend to be small groundwater systems. “These systems typically lack the resources, funding, and infrastructure to effectively manage water contamination, and arsenic — a potent carcinogen — is typically found in groundwater,” says Evans. But larger water systems aren’t necessarily safer. Evans says they also show “consistently elevated risk” because they contain disinfection byproducts, which are a result of required disinfection. “There are contaminants in drinking water that pose health risks other than cancer,” she says. So the disinfection of water is extremely important! And immediate action.
