The goal for our lab activity was to make a silver mirror by reducing silver ions with dextrose. The materials that we used were acetone‚ 5 mL of 1.5 M ammonium nitrate solution (NH4NO3)‚ 5 mL of 0.5 silver nitrate solution (AgNO3)‚ 10 mL of 5% dextrose solution (C6H12O6)‚ 10mL of 10% sodium hydroxide solution (NaOH)‚ a 50 mL beaker‚ a 250 mL Florence flask with a rubber stopper‚ a 10 mL graduated cylinder‚ a waste beaker‚ and distilled water. The first thing we did was rinsed the beaker‚ cylinder
