I am performing coprecipitation reaction, and in the precipitating step, I have a bunch of metal nitrates(ferric nitrate, aluminium nitrate and barium nitrate)in a solution reacting with ammonium bicarbonate.
I need to know the selectivity of these metal nitrates towards the ammonium carbonate and the order in which these metal nitrates will start reacting with the base. I know the Ksp of barium and aluminium nitrate but not of the ferric nitrate. Is there any way of knowing the order in which these compounds will react? How do I proceed with the analysis? Any link to a book or any article will be appreciated.
