What does "6 N hydrochloric acid" mean?
« on: February 25, 2012, 10:59:06 AM »
I came across this in an article:

"The aqueous portion was acidified to pH=2 with 6 N hydrochloric acid. The carboxylic
acid precipitated on standing, was filtered off, and dried under vacuum."

Does it mean 6 drops? 6 molar?

6 Normal . It is the Normality. See Normality here http://en.wikipedia.org/wiki/Normality

6N=6mol/1L

For the specific case of hydrochloric acid. You are equating normality with molarity, which is true in this case but not necessarily true generally.
