Researchers have boosted the efficiency of water electrolysis. Applying a layer of copper atoms in a conventional platinum electrode, reaction intermediates could desorb more easily from the catalyst surface. The modified system generated twice the amount
Redox Review: (Paul Groves) Place a copper-wire shape in a petri dish and add 0.1 M AgNO3 on an overhead projector. The reaction takes a few minutes, so we use the time to write a reaction on the board: Cu + 2Ag+ → Cu2+ + 2Ag Finally, we notice that the TWO ions of silver must be reduced to balance the two electrons lost by the copper atom.
