Maybe some other contributor will help you further, or you can do it the old way and make a trip to the library. clusters (solvents being , or ) have been studied by resonance enhanced two photons ionization, leading to the detection of clusters. Iodide is a good nucleophile, and if it displaces bromide or chloride, NaBr or NaCl will precipitate (these are much less soluble in acetone than NaI). Hydroxides (OH-) are usually insoluble. Chromates (CrO 4 2-) are usually insoluble. The solubility of sparingly soluble salt is reduced in a solution that contains an ion in common with the salt. sodium sulfite Na2SO3 , is soluble in water and will then be a contamination. What is Soluble and Insoluble ? Sodium iodide is highly soluble in water. For essentially ionic compounds, where the dominant factor is the reticular energy, the iodides are the most soluble and the fluorides the least, (ex. – P. 363 • Seidell A.
