Abstract: By using cadmium ion-selective electrode, the existence of complexes consisting of cadmium cation and anion of řrans-crotonic acid in mole ratio 1:1 and 1:2 (CdL⁺ , CdL² ) has been disclosed in aqueous solution of trans-crotonic acid in the pH region 3—5.45. The voltage of a cell comprising a cadmium ion-selective electrode and silver chloride electrode is governed by the equation [....]   The equilibrium constants of formation of complexes CdL⁺ and CdL² were calculated by the method of successive approximation; log {K₁₁₀₀}=1.97 ± 0.07, log {K₁₂₀₀} = 2.33 ± 0.03.
