hi
I've never heard of EDTA at a pH lower than 8.
Sorry can't be of much help. Definitely doesn't dissolve using HCl until you reach very close to 8.

EDTA won't go into solution until you reach pH 8.0.

Di sodium salt of EDTA should dissolve at 7.2. But, i donot the know the probability at 0.5M concentration.
