* In ''Literature/TheStainlessSteelRat'', a character stages a [[GreatEscape prison break]] with an acid that dissolves precise lines through the metal ceiling of the cell like a cutting torch. He does warn the inmate not to touch the edges of the hole on the way up, though.

** Possibly a reference to John Haigh. A real life killer that used acid to dispose of bodies and who was only tied to the murder of one suspect because of the few bodily parts not even the strongest acid can dissolve: teeth and gallstones.

* Many real acids do ''some'' of the things commonly attributed to Hollywood acids. Common acids do dissolve ordinary metals, producing flammable hydrogen gas in the process (though plastic, glass, concrete, and most other common materials are unaffected). The stronger ones can also burn flesh, and produce some very nasty fumes, like smelling vinegar but far stronger. Most acids won't dissolve flesh, though, bases are actually better at this.[[note]]The flesh is made of proteins, which are, in turn, made of thousands of amino acids connected together by a structure known as a peptide bond, -CO-NH- - due to its structure, this bond is susceptible to be broken up by a strong base, like a sodium hydroxide, for example. An acid does such a job, too, but it requires much more time and much higher temperatures to accomplish.[[/note]] However, most of the common acids are clear liquids that look just like water, and they certainly don't bubble continuously for the sake of it.
* Nitric acid looks like plain water until you drop in a piece of material to dissolve, at which point it eagerly plays the trope straight by boiling and bubbling as well as emitting toxic fumes. There's a reason why labs always keep beakers of the stuff under venting hoods and clearly labeled. This, however, refers only to the ''pure'' nitric acid, which, for the reason explained below, is rather rare and expensive. Most ''real'' nitric acid that you can encounter has a significant admixture of nitrogen dioxide ([=NO2=]), a reddish-brown toxic and caustic gas. In fact, even if your sample is pure nitric acid readily decomposes into nitrogen dioxide and water with time, and the higher concentration it is, the faster this process becomes. 95% nitric acid is even called "red fuming nitric acid", because it is deeply orange in color and gives constant brownish-orange fumes of [=NO2=] -- the so-called "fox tail".

** Oddly, hydrofluoric acid is ''not'' considered a strong acid by chemists. Its pH is not nearly as low as hydrochloric acid or sulfuric acid. Hydrofluoric isn't dangerous because of its acidity (I.E. how much of the acid forms hydrogen ions, which is how pH is measured), but because it contains ionic fluorine, the single-most reactive element in the entire periodic table, which will happily (and extremely aggressively) target and react with anything sufficiently electropositive in its vicinity (it is the fluorine, not the hydrogen, that reacts with calcium and causes the health issues associated with hydrofluoric acid exposure).

* The term [[ExactlyWhatItSaysOnTheTin Super Acid]] is used for any material that is more acidic than 100% pure sulphuric acid. For example, some particularly corrosive chemicals can protonate and dissolve hydrocarbons, something that does not occur in a normal acid environment.
* The strongest known superacid is [[http://en.wikipedia.org/wiki/Fluoroantimonic_acid fluoroantimonic acid]], which is ''ten quadrillion'' (10^16) times stronger than pure sulfuric acid. Formed from reacting a 2:1 ratio of hydrogen fluoride and [[http://en.wikipedia.org/wiki/Antimony_pentafluoride antimony pentafluoride]] (both already quite toxic and corrosive by themselves), fluoroantimonic acid can protonate hydrocarbons and like chlorine trifluoride below, reacts violently with water. The reaction to form the acid also produces unstable [[http://en.wikipedia.org/wiki/Fluoronium fluoronium]] (Itself a strong acid) as a byproduct, and is also responsible for fluoroantimonic acid's extreme acidity.
