Formation of a Mirror

A solution is added to a flask. Within seconds a

brilliant mirrored surface forms on the inner wall of

the flask

purpose
Purpose
  • To observe a silver plating reaction
demonstration
Demonstration
  • Sugar was one of the solutions in the flask
  • A silver ion solution was the other solution
  • Oxidation of the carbon occurred when silver ion was reduced
  • The silver metal reduction product adhered to the glass

1. Redox Reactions

2. Selective Organic Reactions

1 redox reactions
1. Redox Reactions
  • In a redox reaction, one substance loses electrons while another substance gains electrons
  • “Redox” is a conventional term which is a combination of the words “reduction” AND “oxidation”
  • The substance that loses electrons is said to be oxidized and/or the reducing agent
  • The substance that gains electrons is said to be reduced and/or the oxidizing agent
2 selective organic reactions
2. Selective Organic Reactions
  • Organic compounds may be totally oxidized to carbon dioxide and water
      • gasoline oxidation (combustion)
  • Organic compounds may be selectively oxidized by adding an oxygen atom to just one carbon
    • C O C O

conclusions
Conclusions
  • The formation of silver metal was due to the reduction of silver ion
  • The reducing agent for silver ion was the sugar
  • The sugar was simultaneously oxidized as the silver ion was reduced
comments
Comments
  • Oxidation (the loss of electrons) of one specie is always accompanied by the reduction (the gain of electrons) of another specie
  • The reaction in this demonstration is the “Tollen’s Reaction” and is a test for the presence of oxidizable sugars
