## Abstract A new polarographic method for determining complex‐stability constants is described. In solutions where the total metal‐ion concentration is equal to the ligand concentration, a relation has been found between the shift of the half‐wave potential and the degree of dissociation. The stab

Abstract
The kinetics of complex formation of Cu^2+^‐tetraphenylporphine in the presence of Mg^2+^, described in a previous paper, are discussed. The rate of formation of Cu^2+^‐ and of Zn^2+^‐tetraphenylporphine has been determined in a buffered system.

## Abstract The kinetics of complex formation reactions have been studied with Tetraphenylporphine. In the presence of Mg^2+^ and Cu^2+^ first the unstable Mg^2+^ complex is formed and afterwards an exchange reaction, yielding the more stable Cu^2+^ complex, takes place.
## Abstract The kinetics of exchange reactions with the Zn^2+^‐, Ni^2+^‐, Co^3+^‐ and Cu^2+^‐complexes of N,N‐Di‐n‐propyl‐dithiocarbamate in acetone have been studied.
## Abstract The exchange reaction of Ni(II)N,N‐di‐propyl‐dithiocarbamate with Cu^2+^ in methylcellosolve has been studied. The actual exchange reaction is much faster than the dissociation of the Ni(II)‐complex. It is therefore assumed that the metalion exchange is brought about through direct coll
