The compound gold (III) iodide, Aul3, has Ksp=1.0 x 1046, and a molar mass of 577.67 g. Write the net ionic
reaction for this compound dissolving in water. What are the molar concentrations of Au3* and of I- in a
saturated solution of gold (III) iodide? What is the solubility (in g/ L) of the compound Aul3 in pure water?
Reaction:
[Au3*) =
M
