Question

Question: Oxidizing chemicals are used as cleaning aides. They work by grabbing electrons that may be holding two atoms together in a covalent bond. When bonding electrons are stolen, the chemical compound is destroyed. Which element in bleach (sodium hypochlorite) works in this manner?

A) Why do concentrated bleach solutions wreck some clothes?

B) why doesn't bleach work very well on a rust stain composed of ferric hydroxide?

C) Many disenfectants also work in the same way, that is by grabbing electrons. What element in hydrogen peroxide is responsible for its disenfecting properties?

D) Why might a very concetrated solution of hydrogen peroxide be dangerous to your skin?

E) How does iodine work as a disenfectant?

F) Why is chlorine gas deadly?

Explanation / Answer

Bleach has dichlorine in it which is a powerful oxidising agent and can take out electrons.

A) Yes, too much bleach causes bleach stains on he clothes. After adding the oxidatkon happens. And if oxidation happens on big molecules they wash away with the clothes.

B)It will not remove the stain but will speed up the rusting. Iron will remove its electron in the presence of strong oxidising agent and the condotion will become worse.

C) The presence of O2^2- in the hydrogen per oxide is strong oxidiser.

D) It is an strong oxidiing agent so high amount of it on skin can corrode your skin.
