KJELDAHLS PROCESS 



13 



The distilling apparatus shown in Fig. 2 avoids the use of a 

 condenser, the steam containing the ammonia delivering directly 

 into the acid. Provided that the solution in the receiving vessel 

 is kept decidedly acid^ there is no danger of loss of ammonia, even 

 when the temperature has reached the boiling-point.

 with condenser. 



With the use of a condenser, as in Fig. 3, even in the event of 

 the liquid in the receiver becoming alkaline owing to the presence 

 of insufficient acid, the result of the determination will not generally 

 be rendered valueless.
