Not true Bill Warner. Water content (over 7H2O content), purity, and
percent of the compound present contribute to the concentration.  So,
thanks to the other postees and to my chemistry background we (I) can only
assume a certain concentration.  That is why I asked.

No chemistry book that I previously looked in had Epsom Salt concentrations
and percentages.  Therefore, I thought APD could help....

No objections at all, and thanks for the reply BTW - I was just trying to
get information in order to try some hardness and alkalinity experiments.
