PPT-The Electrolysis of Aqueous Solutions

The electrolysis of aqueous solutions Aqueous solutions are solutions in water Water is a very weak electrolyte It ionises very slightly to give hydrogen ions and hydroxide ions H 2 O l. 02 OC 08 aqSOA from glyoxal 1 OC 2 aqSOA from methylglyoxal 04 OC 1 brPage 4br CHOCHO CHOH CHOH Aqueous phase CHOCOOH Gas phase COOH eff T OH OH CO k2pH T k3pH T k1T OH OH T OH CHOCOOH CO brPage 5br CHOCHO OH SOA overall T LWC OH Gly dt dSOA ga Putting electrical energy in to force the . nonspontaneous. change. electrolysis.
