A simple.method ie'described:for the determination of,Mn
ions, which:is based on the~formation:of fluoro manganate.
The first experiments with KNO as oxidizing agent in the

proceed quantitatively. Withammonium nitrate however exact
results~were_obtained (Table 1).-
The.determination of
the

The exnerillenta-1 results obtained sho-.~ed (Fifr 2) that the
hyllrolysis of~ (I) is a reaction of the -first order and is
not catal-r-_7ed by hydrogen ions (Table 1), since the molecule
H N:BP possesses no charfre. The function of the rate con-

the various double salts of boron fluoride will be treated
in detail in a later paper. Preliminary e*xperinents showed
thlit thci hydrolysis of the H N:BF is markedly accelerated

as follows:. in solutions, equilibrium may exist between the cyclic and.
the linear form of-,the,trimer anions as well as between the trimer form,
and its depolarization products. The addition of any further OH or

Xirc~tics of the Hy~rolysis of Boron Ammine Trifluoride, SOV/76-33-2-21/45
The exnerillenta-1 results obtained sho-.~ed (Fifr 2) that the
hyllrolysis of~ (I) is a reaction of the -first order and is
not catal-r-_7ed by hydrogen ions (Table 1), since the molecule
H N:BP possesses no charfre. The function of the rate con-

the various double salts of boron fluoride will be treated
in detail in a later paper. Preliminary e*xperinents showed
thlit thci hydrolysis of the H N:BF is markedly accelerated
