Acid Reagents Physical Properties
(Rated as: excellent)

It should be fairly obvious what I'm doing in this digest after the posting of this first part of the table. PLEASE, help if you know how to do the tables, or can arrange the information in an easy manner for me to convert to the table form. THANKS.
