Silicon powder reacts with water liberating hydrogen gas that poses an explosion risk. Adding metal ions with a high reduction potential suppresses hydrogen generation. Copper (II) ions are particularly effective in this regard. In their presence the reaction featured three distinct stages. In the initial phase copper is deposited on the silicon surface concomitant with a rapid drop in the solution pH. Most of the hydrogen evolves during a second active stage with the pH showing a slight upwarddoi:10.1080/00986445.2013.777902 fatcat:hu3bttt5izbvrlbpuuczcimluq
