Depends what kind of Acid is used:
Cu10 (PO4 )6 (OH)2 + 20 H+ => 10 Cu2 + + 6 H3 PO4 + 2 H2 O
but it could be also
Cu10 (PO4 )6 (OH)2 + 2 H+ => Cu10 (PO4 )6 2+ + 2 H2 O
or
Cu10 (PO4 )6 (OH)2 + 2 H+ => 3 Cu3 (PO4 )2 + Cu 2+ 2 H2 O

thx a lot dude

pH 4 means weak acid. So the copper phosphate will precipitate. The last equation I think will take place.
