hydroxide or of oxy-lead acetate to a solution of neutral potassium, 

 sodium, or ammonium oximidosulphonate causes precipitation of an 

 alkaline or ' basic ' salt. Strontium hydroxide gives a precipitate of 

 alkaline salt with potassium oximidosulphonate almost immediately ; 

 it gives no precipitate with sodium or ammonium oximidosulphonate, 

 but causes an alkaline salt to crystallise out in a few hours. 



Decomposition of chlorides and nitrates by the neutral oximidosnl- 

 plionates. — The neutral potassium salt in solution with potassium 

 chloride, potnssium nitrate, or sodium chloride, yields when treated 

 with strong ammonia-water, alkaline oximidosulphonates either at 

 once or after evaporation, ammonium «^hloride or nitrate being formed. 



Decomposition of carbonates and of acetates by the neutral oximidosvl- 

 phonates. — AVhen a warm solution of sodium or potassium carbonate 

 is saturated with the neutral potassium oximidosulphonate, the less 

 alkaline potassium-s;dt or an alkaline potnssium-sodium salt crystal- 

 lises out on cooling. Neutral sodium or potassium oximidosulphonate 

 evaporated with either sodium or potassium acetate gives off acetic- 

 acid vapours and yields a highly alkaline solution (of alkaline 

 oximidosul phonate) . 



Eeconversion of alkaline into neutral and less alkaline 

 oximidosulphonates. 



The conversion of the more alkaline back into the alkaline, and of 

 these aoain into the neutral oximidosulphonates, described in this 

 section, and the conversion of neutral into alkaline oximidosul- 

 phonates, described in the preceding section, demand particular atten- 

 tion as being facts opposed to the view maintained by Claus and by 

 Raschig that Fremy's sulphazotates include the salts of two distinct 

 acids.
