Reference no: EM13185933

Some solid trisodium phosphate, Na3PO4, is added to the solution that is formed by mixing 1L of .002 M Al(NO3)3 and 1L of .004 M CaCl2. Which one is going to precipitate first, aluminum phosphate (Ksp=9.8x10^-21 M^2) or calcium phosphate (Ksp=1.3x10^-32 M^5)? How many grams of trisodium phosphate must be added for the precipitation to occur?
