My 8th gr. nephew is doing a science experiment to see which type/brand
decongestant dissolves faster in the stomach.  He knows he can use hydrochloric
acid and water to simulate stomach acid, but does not know the ratio of
hydrochloric acid to water when mixing, or if other ingredients are needed.  We
know the pH level should be between 1 and 3, however, we don't know how to get
that level.  (We don't know how much hydrochloric acid to use.)  Thank you in
advance if you are able to help him so that he can proceed with his project.
