C1.4.3.1 Hydrogen as a Reducing Agent

Hydrogen as a Reducing Agent In experiment C1.4.3.1, copper oxide is reduced with hydrogen to form elementary copper. Hydrogen is a good reducing agent. Its ability to react applies not only to free oxygen but also to oxygen compounds. The metal is formed in this way when transforming a metal oxide (as in this experiment) with hydrogen.   Components of experiment: 1 664 0772 Reaction tube, quartz, 160 x 20 mm Ø 2 667 286 Silicone stopper, one 7-mm hole, 16...21 mm diam. 1 666 988 Combustion boat, not glazed, 80 x 12 mm 1 665 201 Glass tubes, 80 mm x 8 mm diam., set of 10 pieces 1 665 238 Glass nozzle, 90°, 80 x 80 mm, 8 mm Ø 1 666 714 Cartridge burner, DIN type 1 666 724 Wide-flame attachment 1 604 481 Rubber tubing, 1 m x 4 mm diam., DIN 12865 1 667 198 Silicone tubing, 2 mm diam., 1 m 1 666 602 Base rail, 55 cm 2 301 27 Stand rod, 50 cm, 10 mm diam. 3 666 615 Universal bosshead 3 301 09 Bosshead S 2 666 555 Universal clamp, 0...80 mm 1 ADANBL124E Analytical balance 120 g; 0,0001g, with USB interface 1 664 800 Gas scrubber bottle, lower section, 200 ml 1 664 806 Glass tube insert with filter, ST 29/32 1 604 5672 Double microspatula, steel, 150 mm 1 666 4796 HydroStik PRO 1 666 4797 Regulating valve 1 666 4798 HydroFill PRO 1 672 9500 Copper(II) oxide, powder, 50 g 1 671 8410 Iron wool, 200 g 1 674 7860 Sulfuric acid, 95-98 %, 500 ml   Experiment instructions please click here
