That has got to be one of the hardest mixtures to identify...we were given that one at state (I think, I swear it was, but I can't be 100% sure) and I spent quite some time trying to combine the results from solubility tests to the HCl and... it was bad. XP Now I realize I should've thought about the pH paper... :?
