HCl

[Dante]

Is it really stomach acid (HCl) has pH 6.0-7.0

I remember a few years back our science teacher told us that if we wanted to know what hydrochloric acid tasted of, vomit was the answer. When we vomit, he told us, we bring up partially digested food and stomach acid. He told us that vomit got its taste from the hydrochloric acid.

I've never tasted HCl, but I've smelt it and it smells nothing like vomit.

I found out later that our science teacher had believed and repeated a myth.
