What is the proper chemical formula for the perchlorate ion. Enter the formula by writing the formula followed by a comma and then any charge on the ion. For example: the carbonate ion, CO32- would be entered as CO3,2- (note the comma). Enter singly charged ions, like the hydroxide ion or the lithium ion, as OH,- and Li,+ (omitting the 1).

  • Chemistry -

    Perchloric acid is HClO4.
    The chlorate ion is ClO4,-.
