Investigate the effect of transition metal catalysts on the reaction between iron(III) nitrate and sodium thiosulfate. Includes kit list and safety instructions.

In this experiment, students compare the rate of reaction between iron(III) nitrate solution and sodium thiosulfate solution when different transition metal ions are used as catalysts. The catalysts used are copper(II), cobalt(II) and iron(II) ions.
