• Resumen

  • A silver mirror can be deposited on many types of surfaces from the reduction of the silver−diammine complex by a reducing sugar as proposed by Kemp in this Journal. Three extensions of Kemp’s demonstration that highlight the role of SnCl2 sensitizer in the deposition of a silver mirror on surfaces are presented. The demonstration extensions can be easily modified for audience participation. The results are visually striking and the silver-coated surfaces formed can be kept as decorations. The demonstrations can be used to reinforce diverse concepts such as complex formation, oxidation−reduction reactions, carbonyl and carbohydrate chemistry, nanoscale structures, and use of one-way mirrors in forensics.
