Factors affecting electrolysis

Electrolysis of molten lead (II) bromide The only ions here are Pb2+ and Br- This why lead is deposited and bromine gas is released So at the anode, bromide ions lose electrons to form bromine gas: 2Br- - 2e- - Br2 (g) While at the cathode, lead ions gain electrons to

17.3: Electrolysis of Brine

At the cathode, water is reduced: Figure (PageIndex{1}) Diaphragm or Hooker cell for electrolysis I of brine (schematic). Since chloride ions are removed and hydroxide ions produced by the electrolysis, the electrolyte gradually changes from a solution of sodium chloride to a solution of sodium hydroxide.

Electrochemistry, featuring electrolysis and fuel cells.

2011/7/253.3 Electrochemistry We got most of the way through this subtopic and I asked you to go through the remainder for homework. I thought the electrolysis section might be worthy of a post, as we didn't look into it in great detail. So here goes.. Key Ideas from the
