Discover how transition elements differ in aspects of colour, precipitate formation, changes in oxidation state and equilibria. Includes kit list and safety instructions.

In this experiment, students will get to grips with three transition elements — chromium, molybdenum and tungsten. Students will take the discussion points provided, and come to certain observations about these elements colour, precipitate formation and more.
