48 ELECTROLYSIS AND ELECTROS YN THESIS 



oxygen, carbonic-acid gas, chlorine, sulphuric acid, 

 and perchloric acid. 



Potassium-trichlor-methyl Sulphonate This salt was 

 electrolyzed by Kolbe l in neutral concentrated aque- 

 ous solution and gave the following results: 



The solution became strongly acid and contained 

 free hydrochloric and sulphuric acid. Hydrogen was 

 gradually evolved at the negative pole. After the 

 decomposition was complete the solution contained 

 potassium perchlorate, which was also observed in the 

 case of potassium-trichlor-methyl sulphate. 



Ethyl-sulphuric Acid. Ethyl-sulphuric acid gave, 

 according to Renard, 2 on being subjected to electroly- 

 sis, at the negative pole hydrogen, and at the positive 

 pole acetic acid, some formic acid, aldehyde, and sul- 

 phuric acid. In concentrated solution a greater pro- 

 portion of acetic acid was formed. The potassium 

 salt on electrolysis breaks up, according to Hittorf, 3 

 into K and OSO 2 .OC a H 6 . 



Potassium-isoamyl Sulphate, according to Guthries, 

 is decomposed into oxygen, valeric acid, and sul- 

 phuric acid. 



Potassium Xanthate. C. Schall 4 obtained, by the 

 electrolysis of potassium xanthate in aqueous solution, 

 xanthogen supersulphide, as might be expected:
