NaI NH3 and AgI
why?
I believe all of these compound are ionic. So does that mean they are all strong?

NaI is a strong electrolyte because it will be easily dissolved in water, forming its constituent ions, Na+ and I-. NH3 is not ionic, it is a covalent compound. It isn't a strong electrolyte. AgI will also dissolve in water, forming Ag+ and I-, so it too is a strong electrolyte.

NaI ionizes completely into Na+ and I-, so it is a strong electrolyte. Ammonia reacts 5% with water according to NH3 + H2O ===> NH4+ + OH-, so that is a weak electrolyte. Silver iodide, AgI, is one of the most water insoluble substances known, so it will give vanishingly small amounts of Ag+ and I-, and so that is the weakest electrolyte of the trio.

a strong electrolyte occurs when the solute dissociates completely in a solution. 1. no (fluoride is very electronegative) 2. (no - i don't think organic compounds dissociate much) 3. no 4. yes 5. yes 6. yes
