I cite: "Dissolve 0.075 g (0.100 mmol) of Ru(bpy)3Cl26H2O in 50 mL of deionized water in a 100-mL beaker. Add ca. 1 g (40 mmol) of (NH4)2S2O8 with stirring, followed by 50 mL of acetonitrile. Adjust the pH of the solution to 1.2 (±0.05) with 2 M HCl. This solution is stable for more than 24 hours. When you wish to begin the demonstration turn out the room lights and add the magnesium powder or tailings (ca. 1 spatula tipful) with very vigorous stirring (e.g., using a Teflon-covered magnetic stir bar and stir plate) so that the magnesium is suspended and visible. When the magnesium is added an orange glow will be produced around the metal."
