Sodium thiosulfate (sodium thiosulphate) is an inorganic compound with the formula Na 2 S 2 O 3 ·(H 2 O) x. Typically it is available as the white or colorless pentahydrate (x = 5), which is a white solid that dissolves well in water. The compound is a reducing agent and a ligand, and these properties underpin its applications. [2]
The time required to remove half of the chloramine from 10 US gallons (38 L; 8.3 imp gal) of water by boiling is 26.6 minutes, whereas the half-life of free chlorine in boiling 10 gallons of water is only 1.8 minutes. [16] Aging may take weeks to remove chloramines, whereas chlorine disappears in a few days. [17] [18]
Chloramines are responsible for the distinctive "chlorine" smell of swimming pools, which is often misattributed to elemental chlorine by the public. [ 9 ] [ 10 ] Some pool test kits designed for use by homeowners do not distinguish free chlorine and chloramines, which can be misleading and lead to non-optimal levels of chloramines in the pool ...
Sodium thiosulfate is an effective chlorine neutralizer. Rinsing with a 5 mg/L solution, followed by washing with soap and water, will remove chlorine odor from the hands. Rinsing with a 5 mg/L solution, followed by washing with soap and water, will remove chlorine odor from the hands.
They are also used to eliminate both free chlorine and the more stable form, chloramine, from water solutions (e.g., drinking water from municipal sources). Campden tablets allow the amateur brewer to easily measure small quantities of sodium metabisulfite, so they can be used to protect against wild yeast and bacteria without affecting flavour.
Chloramine gas is created when these two chemical products are mixed and can adversely affect the respiratory system, and provoke nausea, and watery eyes. ... If an awful smell comes from the ...
Inorganic chloramines are produced by the reaction of ammonia and hypochlorous acid or chlorine. An urban legend claims that mixing household bleach (aqueous sodium hypochlorite) with ammonia-based cleaners releases chlorine gas or mustard gas; in reality, the gas produced by the reaction is a mixture of inorganic chloramines.
When hosting a dinner party, lingering odors from long hours of cooking in the kitchen can be an issue. Cooking odors from fish, onion, garlic, burnt foods and fried foods can last especially long.
