For the cl- acid Fajans 2 found k = 0.00114, and for the 

 1-acid k = 0.00115. 



On account of the relatively high rate of decomposition of 

 bromcamphor-carboxylic acid in the presence of bases, solutions 

 of the acid and the base were prepared saparately ; on starting 

 an experiment the solution of the acid was placed in the 

 reaction flask, nitrogen bubbled through so as to remove any 

 carbon-dioxide and air from the apparatus, and then 1 ccm. of 

 the solution of base, containing the required amount of the 

 substance, was added to the acid solution in the reaction flask. 

 The two solutions were thoroughly mixed by shaking and the 

 flask immediately lowered into the thermostat. 



The liquid was measured at room temperature.
