[47] [48] It may be made by diluting household bleach as appropriate (normally 1 part bleach to 9 parts water). [49] Such solutions have been demonstrated to inactivate both C. difficile [47] and HPV. [50] "Weak chlorine solution" is a 0.05% solution of hypochlorite used for washing hands, but is normally prepared with calcium hypochlorite ...
In pH testing of bleach substances, sodium thiosulfate neutralizes the color-removing effects of bleach and allows one to test the pH of bleach solutions with liquid indicators. The relevant reaction is akin to the iodine reaction: thiosulfate reduces the hypochlorite (the active ingredient in bleach) and in so doing becomes oxidized to sulfate ...
I typically grab my spray bleach cleaner and sponge to disinfect my kitchen sink once or twice weekly. But the pungent smell of bleach, a caustic chemical near food prep, and the fact that I ended ...
An antichlor is a substance used to decompose residual hypochlorite or chlorine after chlorine-based bleaching, in order to prevent ongoing reactions with, and therefore damage to, the material that has been bleached.
Sure, you think, I’ll just pour some bleach on the grout lines and problem solved. Stop right there. Bleach may make the grout lines look better but it won’t get to the bottom of the problem ...
This is achieved by the action of bleach activators, such as tetraacetylethylenediamine and sodium nonanoyloxybenzenesulfonate, upon hydrogen peroxide formed from sodium percarbonate in water. The peracetic acid is a more effective bleaching agent than hydrogen peroxide itself.
With the formula 4Na 3 PO 4 ·NaOCl·44H 2 O the material called chlorinated trisodium phosphate is used as a disinfectant and bleach, like sodium hypochlorite. It is prepared using NaOCl in place of some of the base to neutralize phosphoric acid. [7]
The hypochlorites in liquid bleach and bleaching powder can react with ammonia to form a number of products, including monochloramine (NH 2 Cl), then dichloramine (NHCl 2) and finally nitrogen trichloride (NCl 3). Similar reactions may occur with amines or related compounds and biological materials (such as urine). The result depends on the ...
