A movie depicting a reduction of Tollen's reagent (an ammoniacal silver nitrate complex) by glucose solution to form silver mirror. Glucose is oxidized to gluconic acid. This reaction is used as a test for aldehyde groups in organic chemicals (as well as for making silver mirror), which includes formaldehyde, acetaldehyde and glucose.

    this is such an awesome test

  • The hot water was used to warm the mixture up and to get a steady rated reaction to form the mirror.

  • WOW! From what I've read, this is almost impossible to do correctly.. congratulations and many thanks..
