Hi there, So when I am justifying, do I have to write the dissolution equations for all 3 of them eg. NaCl > Na+ + Cl - etc. and then do I write the hydrolysis equations for each of them ? also for ammonium nitrate, why cant the anion NO3 - react with water to form HNO3 and OH - ions ?

please help with justifying which ones are acidic or neutral or basic, I have trouble figuring out how the equations for dissolution works.
