Will silver hydroxide dissolve in excess NaOH(aq) or NH3(aq)?

Answer 1

AgOH will dissolve in excess NH3 to form Ag(NH3)2+ complex, it won't form a stable complex with OH- so it will not dissolve in excess NaOH. The ability to form complex depends on their dissociation constant and solubity product.

Answer 2

AgOH is not acidic or amphoteric, so will not dissolve in NaOH.
With ammonia, the very soluble complex ion [Ag(NH3)2]+ forms, so the hydroxide will dissolve in ammonia.

Answer 3

I am pretty sure that it will desolve in NaOH because the silver hydroxide is a polar ionic compound, and the general rule is that polar substances dissolve in polar substances, and that is NaOH. (NH3 is non-polar (Covalent bonds)
