Which salt is the MOST difficult one from which to extract silver cation from its ionic lattice into solution?
AgCl, AgNO3, AgBr, or Ag2CO3
the answer is AgBr. all solubilities are given except for AgNO3 and Ag2CO3.
Nitrate salts are soluble, but how would I know that AgBr is less soluble than Ag2CO3 without solubility values?
I found this question which seems to be similar online that I think gets to the root of my confusion because I don't know the answer to it:
Bromide ion is the conjugate base of a strong acid; carbonate ion is the conjugate base
of a weak acid. How do these facts correlate with the theory/experiment results for silver
bromide and silver carbonate? Do you expect silver carbonate to be more or less soluble
than the Ksp calculation would predict? Why?
any help would be appreciated.
