How do you tell which set of elements forms a precipitate? So, if I have: Ba2+(aq) + 2Cl-(aq) + Ag+(aq) + NO3 2-(aq) Which forma the precipitate? Is it AgCl2 because it has fewer ions to bond? Or is it BaNO3? And why?

All alkali metals are soluble 
All ammonium is soluble 
All nitrates and acetate are soluble 
All halides are soluble if they are not Hg Ag and Pb 
All sulphate are soluble when not in combination with Ba Sr Ca Hg Ag or Pb 
All carbonated hydroxides oxides and phosphates are insoluble except when in combination with ammonium or and alkali metal 

Therefore BaNO3 is soluble as it contains a nitrate and AgCl2 is insoluble as it contains Ag
