Carry out two redox reactions and observe and interpret the results in this microscale class practical. Includes kit list and safety instructions.

In this experiment, students observe and interpret two redox reactions using microscale apparatus. First, students investigate the reaction between copper(II) ions and halide ions, adding drops of copper(II) sulfate solution to sodium chloride, potassium bromide and potassium iodide. They then explore the reaction between silver(I) ions and iron(II) irons using silver nitrate solution and iron(II) solution.
