    Kodak F-5a

    Water, about 125ºF (50ºC) - 20 fl. oz. - 600mL - 25 fl. oz.
    Sodium Sulfite, desiccated - 2 1/2 oz. avdp. - 75g - 3 oz. avdp.
    Acetic Acid (28%) - 7 1/2 fl. oz. - 235.0mL - 9 3/8 fl. oz.
    Boric Acid, crystals - 1 1/4 oz. avdp. - 37.5g - 1 1/2 oz. avdp.
    Potassium Alum - 2 1/2 oz. avdp. - 75.0g - 3 oz. avdp.
    Cold Water to Make - 32 U.S. fl. oz. - 1.0L - 40 Imp. fl. oz.

    U.S. Customary and metric measures given are exact. Imperial measures are accurate to within 1/16 oz. avdp, with liquid measures being exact in the proportion of 4 U.S. fl. oz. : 5 Imp. fl. oz.

    If it is desired to mix a stock hardener solution, use Kodak F-5a, adding one part of cool hardener to four parts of cool 30% hypo solution--2.5 pounds (3 pounds if Imperial rather than U.S.) of hypo to the gallon of solution.

    The information is in the Kodak publications.

    Why does it have that bit about a stock hardener ? F5a is an acid hardening fixer.
