  1. OB: Single Replacement Reactionsor, connecting my love for Janet to Table J Take out Reactions HW #1 first, check over, grade yourself out of TEN, inbox it before you go. Take out Table J too. For A Good Time Click Here: HW #1 answers

  2. Single Replacement reactions (SR) starts with an aqueous solution and atoms being added to it. In this reaction, the atoms may have a high enough reactivity level to replace an ion in solution, bumping it out as a precipitate. Example… A(S) + BC (AQ) AC(AQ) + B (S) The atom A is put into the aqueous solution BC. A bumps B out of solution, forming a new solution AC, and B falls out of the solution as a solid precipitate. Predicting these reactions requires the Activity Series (Table J)

  3. Demo #1 (not demo diagram) Mg(S) metal added to HCl(AQ) solution Mg(S) + HCl(AQ) There are 3 parts to this reaction so far, the atom (Mg), the cation (H+1) and the anion (Cl-1) Two of these must be on one side of table J, and those two are???

  4. Mg(S) + HCl(AQ) It’s the Mg and H that are both on the left side of the table. Since Mg is higher up, that means Mg has a higher activity level, it will have the ability to bump the hydrogen cation out of solution. When that happens, the reaction occurs, forming???

  5. Mg(S) + HCl(AQ) MgCl2(AQ) + H2(G) Now we have to balance this. Mg(S) + 2HCl(AQ) MgCl2(AQ) + H2(G) Ratio 1:2:1:1, John Dalton is still happy.

  6. Demo Diagram #3, SINGLE REPLACEMENT REACTIONS Abstract A(S) + BC (AQ) AC(AQ) + B (S) Word Equation: copper into silver nitrate solution reacts Cu(S) + AgNO3(AQ) ??? Looking at the ATOM, CATION, and ANION, it’s clear that the Cu and the Ag are on the left side. Since the Cu is higher on the table than Ag, Cu will jump into solution, bumping the silver out as a precipitate.

  7. Do demo for demo diagram NOW… Cu(S) + AgNO3(AQ) Ag(S) + CuNO3(AQ) Looking at the ATOM, CATION, and ANION, it’s clear that the Cu +the Ag are on the left side. Since the Cu is higher on the table than Ag, Cu will jump into solution, bumping the silver out as a precipitate. It’s already balanced (which is nice for us) Products: solid silver precipitate & Copper(I)nitrate

  8. Love and Table J, Charlie gets married with a band of Gold (Au) from Janet…

  9. Charlie’s Wedding Band Made of Solid gold! HCl(AQ)

  10. Table J tells us when reactions will happen, or not. Au(S) + HCl (AQ) no reaction Why? Because Au is lower on table J than H is, Gold is not active enough to bump out the hydrogen from solution! My wedding band is too important to leave to chance!

  11. Balance these SR reactions or write an X for no reaction Mg(S)+ Zn(NO3)2(AQ) Na(S) + Sn(NO3)2(AQ) Cl2(G)+ KBr(AQ)

  12. Balance these SR reactions or write an X for no reaction Mg(S)+ Zn(NO3)2(AQ) Mg(NO3)2(AQ) + Zn(S) Na(S) + Sn(NO3)2(AQ) NaNO3(AQ) +Sn(S) Cl2(G)+ 2KBr(AQ) 2KCl(AQ) + Br 2(L) This last one is special! Note that it’s the anions that get replaced. Remember, two of the three parts are always on one side of table J (OR THE OTHER) Watch out. Also, the phase symbol here for bromine might be gas, or liquid, or even solid, we have no clue as to the temperature. I suppose any phase symbol could be correct, but no phase symbol is wrong.

  13. Balance these SR reactions or write an X for no reaction Zn(S)+ H2SO4(AQ) Li(S) + Sn(NO3)2(AQ) Au(S)+ KCl(AQ)

  14. Balance these SR reactions or write an X for no reaction Zn(S)+ H2SO4(AQ) ZnSO4(AQ) +H2(G) 2Li(S) + Sn(NO3)2(AQ) 2LiNO3(AQ) +Sn(S) Au(S)+ KCl(AQ) NO REACTION, gold is below potassium on table J (silly)
