Product Details

Beautiful silver chemistry "mirrors" real-life applications of oxidation and reduction! Students create microscale silvered culture tubes by reacting silver-ammonia complex ions with dextrose. Dextrose is a reducing sugar—it reduces silver ions to silver metal, coating the inside of the glass tube with a durable, reflective silver mirror. The reaction was first used to produce mirrors by the German chemist, Justus von Liebig, in 1835, and is still used for that purpose today. It's also the basis of a classic qualitative test in organic chemistry. Combine history with current applications of chemistry and reinforce principles of oxidation, reduction, and organic chemistry, all in one very effective lab activity. Super Value Kit is complete with materials to plate 75 small culture tubes.
