LAB 12. THE NINE BOTTLES EXPERIMENT AN ANDVENTURE IN CHEMICAL DENTFICAT?ON SESSION 1 PRE-LABORATORY ASSIGNMENT 1 The chemical equations below represent pairs of solutions being mixed in this experiment. Use the solubility rules, the equations that produce a gas or a non electrolyte and any other resource available to predict the products of the reactions and their physical appearance. If any of the "mixtures DO NOT give a reaction, write "No reaction". For those "mixtures" that DO give a reaction, write the balanced molecular, total ionic, and net ionic equation. Be sure to include the proper physical states; solid (s), liquid (1), gas (g) or aqueous solution (aq) in your equations. Then using these results, you will fill out the grid below by recording your predicted observations in each box. Only fill in the intersecting columns and rows for reactant pairs that you predict will yield product. See example in grid below. Use abbreviations such as ppt for precipitate, wh for white, yw for yellow, ?.?. for heat evolved, etc. Since you will be handing in both pre-lab assignments, make a copy of all your work for comparison with both your known and unknown nine bottle experimental results 4 (ag 4. AgNONa,CO ) 3 (aq) 5. AgNO)NaOH )Explanation / Answer
1) 2 AgNO3(aq) + H2SO4(aq) ------------- Ag2SO4(s) + 2 HNO3(aq)
2 Ag+(aq) + 2 NO3-(aq) + 2 H+(aq) + 2 SO4-2(aq) -------------- Ag2SO4(s) + 2 H+(aq) + 2 NO3-(aq)
2 Ag+(aq) + SO4-2(aq) ------------ Ag2So4(s).
2) AgNO3(Aq) + NH4Cl(aq) ----------- AgCl(s) + NH4NO3(Aq)
Ag+(aq) + NO3-(aq) + NH4+(aq) + Cl-(aq) ----------- AgCl(s) = NH4+(aq) + NO3-(aq)
Ag+(aq) + Cl-(aq) ------------ AgCl(s)
3) 3 AgNO3(aq) + Na3Po4(aq) ---------- Ag3PO4(s) + 3 NaNO3(aq)
3 Ag+(aq) + 3 NO3-(aq) + 3 Na+(aq) + PO4-3(aq) ----------- Ag3Po4(s) + 3 Na+(aq) + 3 NO3-(aq)
3 Ag+(aq) + PO4-3(aq) ------------------- Ag3PO4(s)
4)
2 AgNO3(aq) + na2CO3(aq) ------------ Ag2CO3(s) + 2 NaNO3(aq)
2 Ag+(aq) + 2 NO3-(aq) + 2 Na+(aq) + Co3-2(aq) ------------ Ag2Co3(s) + 2 Na+(aq) + 2 NO3-(aq)
2 Ag+(aq) + CO3-2(aq) ----------- Ag2CO3(s)
5)
AgNO3(aq) + NaOH(aq) ------------- AgOH(s) + NaNO3(aq)
Ag+(aq) + NO3-(aq) + Na+(aq) + OH-(aq) ------------ AgOH(s) + Na+(aq) + No3-(aq)
Ag+(aq) + OH-(aq) --------------- AgOH(s).
