Hydrogen peroxide acts as a bleaching agent because it is a strong oxidizer. Because colored compounds are often caused by conjugated electrons or metal complexes, adding an oxidizer which destroys these compounds causes removal of the color.
Bromine can be used as an bleaching agent but commercially available bleach usually contains Sodium hypochlorite (NaClO)
it is used as a bleaching agent but in the presence of moisture
bleaching agent
sodium hydroxide is a reducing agent and is a strongly alkaline caustic used in manufacturing soap.
Hydrogen peroxide, H2O2, is a powerful oxidizing agent. There are some interesting things going on with this odd substance, and a link is provided to the Wikipedia article on this chemical compound.
No these formulae do not represent the same compound as the suffixes, the numbers against the elements are different. H2O is water, HOH H2O2 is hydrogen peroxide, HO-OH, a reactive bleaching agent.
yes it is a bleaching agent
due to strong oxidizing agent
H2O2 is drinkable, it's hydrogen peroxide but it's poisonso you can't drink it. It's a very good antiseptic and bleaching agent (good for bleaching hair) and is sometimes prescribed as a mouthwash for mouth sores.I've never seen it sold at more than 6% concentration and even that can burn skin so you can appreciate that it's a very powerful oxidizing chemical.
No, H2O is just normal water, H2O2 (hydrogen peroxide) is a very toxic, reactive, oxidative, bleaching chemical.
When H2O2 serves as an oxidizing agent, the oxygen is reduced to H2O. When H2O2 serves as a reducing agent, the oxygen is oxidized to O2 and bubbles are noticed.
Bromine can be used as an bleaching agent but commercially available bleach usually contains Sodium hypochlorite (NaClO)
When H2O2 acts as an oxidizing agent, the H2O2 must be reduced. Therefore, the product from it will be water, in which oxygen has an oxidation number of -2, whereas in H2O2 has an oxidation number of -1 and in O2 the oxygen has an oxidation number of 0.
Yes you can
chlorine gas
ask your teacher
