1a. For each combination of two aqueous solutions, predict whether or not a precipitate (solid product) will form. Put a check mark by those reactions that WILL form a precipitate. options: Na2CO3 and CaCl2 NH4NO3 and SrCl2 KI and PbNO3 KBr and NH4Cl 1b. Kidney stones generally form from the double displacement reaction of two salts that form an insoluble compound, a precipitate. Which of the following salts will react in a double displacement reaction with Na3PO4 to form an insoluble precipitate(s): Potassium chloride (KCl) Potassium carbonate (K2CO3) Magnesium sulfate (MgSO4) Oxalic acid (H2C2O4) Sodium acetate (CH3CO2Na) 1c. Dibasic sodium phosphate dihydrate (Na2HPO4⋅2H2O) is one of the compounds you may consider using. When it is dissolved in water, which ions will be present in significant amounts in solution? Select all that apply. Na2^+ HPO4^-1 HPO4^-2 PO4^-1 O4^-1 Na^+ PO3^-1 H^+ OH^-
