Why isn't vomit corrosive?

Question

Vomit comes from gastric acid, right? And in gastric acid there is HCl and HCl is corrosive (strong), how come when I vomit, it doesn't destroy things that it (as the vomit) hits (such as floor, table)?

Answer 1

The cells responsible for producing the HCl in your stomach are the parietal cells, and the solution they secrete has a concentration of 160 millimoles per liter -- in other words, 0.16 moles per liter, corresponding to a pH of 0.8.

So, low molarity is the answer to your question.
