Solution:- #1.(a): In order to find which one will form a solid precipitate, we have to write the chemical equation and refer the solubility chart. arrow_forward Step 2 The chemical equation for each of the options is: Na2CO3(aq) + CaCl2(aq)  ----> 2NaCl(aq) + CaCO3(s)   (Forms a precipitate)   2NH4NO3(aq) + SrCl2(aq)  ----> 2NH4Cl(aq) + Sr(NO3)2  (Both soluble, no precipitate is formed) 2KI(aq) + Pb(NO3)2(aq)   -----> 2 KNO3(aq) + PbI2(s)  (Forms a precipitate)  KBr(aq) + NH4Cl(aq)    -----> KCl(aq) + NH4Br(aq)  (Both soluble, no precipitate is formed) arrow_forward Step 3 #1(b): The double displacement reaction for each of the salt with Na3PO4(aq) are: 3KCl(aq) + Na3PO4(aq)   -----> 3NaCl(aq) + K3PO4(aq)  (Both soluble, no precipitate is ...
