Data on density, viscosity, and specific electric conductivity of tern
ary iron(III) nitrate-nitric acid-water system solutions are presented
for wide concentration and temperature ranges. Equations for calculat
ing these properties have been derived, and interaction between the co
mponents has been characterized. Solubility of Fe(NO3)3 in the system
studied has been investigated at 283-313 K over wide ranges of acid an
d salt concentrations.
