Silver Iodide in NH3 ... why does it not dissolve?? OCR [PLEASE HELP]

I know that it doesn't dissolve in any concentration of ammonia (conc / dilute) but why is this the case?

Is this even necessary for the spec?

Thanks.

I don't believe we need to know - just the fact that it doesn't dissolve in ammonia

You don't need to know why. You just need to know it doesn't

Because the change in Gibbs free energy is positive for the process

i.e. dissolution would not increase the entropy of the universe ...

Possibly because of the low hydration enthalpy of the iodide ion (due to its large size) ...
