TITANIUM. Q3 



acid, and sulphuric acid poured into the solu- 

 tion. A combination of titanic acid and sul- 

 phuric acid precipitated. It was washed, dried, 

 dissolved in muriatic acid, and analyzed by 

 throwing down the titanic acid by ammonia, 

 and the sulphuric ^acid by muriate of barytes- 

 The constituents were 



Sulphuric acid 7*78 or 5 

 Titanic acid 76-83 - 49'377 



Water . 15-39 - 9'890 



100-00 



It was probably a compound of 



1 atom sulphuric acid 



8 atoms titanic acid 



9 atoms water 



63-125 



If we take Rose's analysis as perfectly exact, 

 then the atomic weight of titanic acid will be 



By a similar process he obtained a combina- an . d oxalic 

 tion of titanic acid and oxalic acid, a white com- 

 pound, composed (from a mean of two analyses) 

 of 



Oxalic acid 1 0-4-05 or 4'5 



Titanic acid 74-095 - 32-045 



Water . 15-500 - 6-703 



100-000
