Presentation Transcript

  1. OB: redox class #3Lots more practice with voltaic cells Starting with a standard issue voltaic cell set up, label it as shown in the next slide, show all the moving parts: oxidation side, reduction side, electron flow, solution charges, salt ion movement to offset solution charges, label anode and cathode, write half oxidation and half reduction reactions, write net ionic equation too.

  2. bulb NaI(AQ) Rb Cs RbF(AQ) CsCl(AQ) ½ ox: _________________________________ ½ red: __________________________________ NET IONIC EQ: ________________________________________ Also name the two solutions and the salt properly.

  3. anode bulb cathode NaI(AQ) Na+1 I-1 e-1 e-1 Rb Cs Cs+1 Rb+1 RbF(AQ) OX CsCl(AQ) RED ½ ox: Rb° Rb+1 + 1e-1 ½ red: Cs+1 + 1e-1 Cs° NET IONIC EQ: Rb° + Cs+1 Rb+1 + Cs° Rubidium fluoride, cesium chloride solutions, with sodium iodide salt solution.

  4. bulb Al2(CO3)3(AQ) Ba Sr Ba(NO3)2(AQ) Sr(OH)2(AQ) ½ ox: _________________________________ ½ red: __________________________________ NET IONIC EQ: ________________________________________ Also, name the two solutions and the salt properly.

  5. anode bulb bulb cathode CO3-2 Al2(CO3)3(AQ) Al+3 e-1 e-1 Ba Sr Ba+2 Sr+2 Ba(NO3)2(AQ) OX Sr(OH)2(AQ) RED ½ ox: Ba° Ba+2 + 2e-1 ½ red: Sr+2 + 2e-1 Sr° NET IONIC EQ: Ba° + Sr+2 Ba+2 + Sr° Barium nitrate and strontium hydroxide solutions, aluminum carbonate salt solution.

  6. bulb Li3(PO4)(AQ) Ag Ti AgHCO3(AQ) Ti2(CrO4)3(AQ) ½ ox: _________________________________ ½ red: __________________________________ NET IONIC EQ: ________________________________________ Also name the two solutions, and the salt, properly.

  7. bulb cathode anode Li+1 Li3(PO4)(AQ) PO4-3 e-1 e-1 Ag Ti Ag+1 Ti+3 AgHCO3(AQ) RED Ti2(CrO4)3(AQ) OX ½ ox: Ti° Ti+3 + 3e-1 ½ red: 3Ag+1 + 3e-1 3Ag° NET IONIC EQ: Ti° + 3Ag+1 Ti+3 + 3Ag° Silver hydrogen carbonate and titanium (III) chromate solutions, with lithium phosphate salt solution
