  • The name of this compound is copper (I) dihydrogen phosphate.

    The formula for the phosphoric acid is H3PO4. When one hydrogen is taken off, the result is dihydrogen phosphate ion whose charge is -1. Therefore, in this compound, copper ion has the charge of +1, hence Roman numeral "I".

  • The anion is dihydrogen phosphate and has a single negative charge. The single copper atom must have a single positive charge to balance, so the compound is copper(I) dihydrogen phosphate.

  • cuprous dihydrogen phosphate is a correct name for it, but there is a better one.
