John are you sure of this?  I would have thought that by "dehydrate" the 
translator might have meant "without water" which would have been 
"anhydrate" and I understand that most recipes assume anhydrate when 
they specify the concentration.  My limited knowledge of chemistry tells 
me that the only difference between the 2 when making up aqueous 
solutions is that the heavier dihydrate molecule would call for a very 
slightly greater proportion of oxalic acid.  Perhaps a chemist out there 
could confirm this and perhaps even tell us how mush more dihydrate is 
needed.
