Why is bleach toxic?

Bleach is a corrosive, especially to metal surfaces. Bleach itself is readily diluted with water and can be neutralized on surfaces, including skin, with sodium thiosulfate (if necessary). Direct reaction: Bleach reacts with biological tissues, causing irritation and cell death by protein denaturation.

What is the most violent chemical reaction?

Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state. This material is both highly reactive and highly explosive.

Can acid eat through glass?

In short, acid can dissolve glass. However, only a few acids, mainly acids containing the element fluorine, are corrosive enough to properly dissolve glass. An example of this is hydrofluoric acid, which is able to react with the compound silicon dioxide found in glass, thus dissolving it.
