    k+2, Cr2O7-2

    H+, HSO4- (which also forms some H+ SO4-)

    Na+ , 2H+, PO4-3

    Na+ PO4-3?? this compound should be (Na)3PO4 or already ionic.

    Dr. J's answer and your question has a flaw: there is no compound NaPO4....there is Na3PO4 and Na2HPO4 and NaH2PO4...in each of which the sodium has a charge of +1....The phosphate ion always has a charge of +3
