This page describes and explains, with fully worked out examples, methods of calculation involving moles, masses or volumes of gases formed in an electrolysis process. You need to understand electrode equations, interconvert mass and moles and use the molar volume where gases are formed at the electrodes in electrolytic processes.

In an actual case of seawater electrolysis using an SOEC, spray injecting seawater into a heated chamber to provide the required moisture content in the feedstock gas is one of the most practical ways. By directly using seawater, there is a high possibility of contamination by sea salt in the fuel electrode.

Yes we do! There are a few methods known to extract gold from seawater. The simplest one is the old technique of electrolysis. By maintaining the right amount of voltage difference between the electrodes, we can separate the gold ions from the electrolyte (seawater) without hydrolyzing the water.

Jun 25, 2018· If searching for gold, this ROV wouldn't find it. Gold in the ocean is so dilute that its concentration is on the order of parts per trillion. Pictured above, the ROV Deep Discoverer investigates the geomorphology of Block Canyon in the Atlantic Ocean. Ocean waters do hold gold, but it's difficult ...
