Answer #1

AgNO3+NaCl----------------> AgCl (ppt) + NaNO3

CaCl2+K2CO3 -----------------> CaCO3 (ppt) + 2 KCl

SrCl2+Na2SO4---------------------> SrSO4 (ppt) + 2NaCl ((ppt) = prcipitate)

NaNO3+AgCl ----------------------> no reaction

Aqueous solutions of CaCl2 and Na2CO3 mix to form a precipitate:

Ca+2 (aq) + CO3-2 (aq) ---------------------> CaCO3 (s)

Aqueous solutions of Pb(NO3)2 and NaCl mix to form a precipitate.

Pb+2 (aq) + 2 Cl- (aq) -----------------> PbCl2 (s)

Aqueous solutions of AgNO3 and Na2CrO4 mix to form a precipitate.

2 Ag + (aq ) + CrO4-2 (aq) ------------------> Ag2CrO4 (s)

Concept: During the first week of this project, you need to synthesize several common kidney stones by precipitation reactions (Make sure that you save the kidney stones for week 2). You need to choose the reactants in a way that the kidney stone is the only product that precipitates out from the solution, while all other products remain soluble in water. This way the precipitate (kidney stone) can be separated from the rest of the solution by either filtration or...
