✦ Synopsis

The effect of the ionic form of the sulfonic acid cation-exchange resins of different degree of crosslinking and of the added sulfuric acid on the equilibrium exchange of four cinchona alkaloid sulfates as well as the equilibrium uptake of four cinchona alkaloid bases by the hydro en form of the same resins from six aliphatic alcohols has been stufied and rhe results are discussed.

ARLIER (1) the equilibrium exchange of four cation-exchange resins of different degree of E cinchona alkaloid (quinine, quinidine, cin-crosslinking and particle size in hydrogen form chonine, and cinchonidine) sulfates on styrene had been studied. This includes the study on the divinylbenzene copolymer based sulfonic acid effect of the ionic form of such resins and of added

## Abstract The kinetics of reversible complexation of oxalatopentaammine cobalt(III) with Ni^2+^ has been investigated in MeOH + water media (0–50 (v/v) % MeOH) at 15.0–35.0Β°C and I = 0.10 mol dm^βˆ’3^. Analysis of rate data indicates that the monobonded complex [(NH~3~)~5~ Β· CoOCOCO~2~Ni]^3+^ in wh
