Reading this with interest RE: [Histonet] normal and molar solutions

[Smith, Allen]

The principal problem with normality is sloppy usage.  A solution of xyz can
be 1 molar, but it cannot be just plain 1 normal: it must be 1 normal in x
or y or z.  Normality is the concentration of the reactive species.
Normality is a useful concept if it is expressed correctly.

Thanks to Gary for handy website.  Hrapchak and Sheehans histotechnics books
and plus other histobooks tell you how to calculate these solutions and
often have charts telling normality and molarity for common chemicals. If
this helps, use it! 

My physical chemist husband suggested that anytime I write up a protocol or
publication requiring normal solutions, that I convert these to molar
solutions. This is what he does, and it is so much simpler for everyone! Ahh
the joys of basic chemistry!
