Question

Please indicate for every reactions where equal amounts of chemicals (all in aqueous solutions) are mixed and either produce a precipitate (ppt) or no reaction (NR) 0.1 M AgNO3 with 0.10 M KI [Choose [Choose) 0.1 M Pb(NO3)2 with 0.10 MKI NR 0.1 MMgSO4 with 0.1 M NaC2H302 ppt 0.1 M Na3PO4 with 0.1 M Ca(NO3)2 [Choose 0.1 MMgSO4 with 0.1 M BaCl2 [Choose 0.10 M NH4Cl with 0.1 M Ca(NO3)2 Choose 0.10 M CoCl2 with saturated CaOH)2 Choose

Answer 1

(i)  AgNO₃(aq) + KI(aq) → AgI(s) + KNO₃(aq)

ppt will form

(ii) Pb( NO3)₂ (aq) + 2KI(aq) → PbI₂ (s) + 2KNO₃(aq)

ppt will form

(iii) No reaction

(iv) Na3PO4 (aq) + Ca(NO3)2 (aq) => Ca3(PO4)2 (s) + NaNO3 (aq)

ppt will form

(v) MgSO4(aq) + BaCl2(aq) --> BaSO4(s) + MgCl2(aq)

ppt will form

(vi) Ca(NO3)2 (s) + 2 NH4Cl (s) ---> 2 N2O (g) + CaCl2 (s) + 4 H2O (g)

ppt will form

(vii) CoCl2 (aq) + Ca (OH)2 (aq) -> Co(OH)2 (s) + CaCl2 (aq)

ppt will form

Your one thumbs up will help me lot. Thanks!
