8 DETECTION AND DETERMINATION OF ALCOHOLS, ETC. 



(3) A 100 cc solution containing 0.243 gram of formic acid; plati- 

 num reduced, 0.517 gram = 0.244 gram of formic acid, 100.4 per cent 

 recovery. 



(4) A 100 cc solution containing 0.1215 gram of formic acid; 

 platinum reduced, 0.255 gram = 0.120 gram of formic acid, 98 per 

 cent recovery. 



The electric conductivity of formic acid is so much greater than 

 that of other similar organic acids that it seems possible to base a 

 method for its determination on that property. A further study of 

 this problem is in progress.
