STUDIES ON THE BEHAVIOUR OF BI-UNIVALENT SALTS IN AQUEOUS SOLUTION. PART V. CADMIUM ACETATE

The nature of cadmium acetate has been studied from the E. M. F. measurements of the cells--

       (A)       \(Cd_xHg_y| Cd(NO_3)_2|| bridge||\)\(\begin{smallmatrix} Cd Ac_2(c) \\ HAc(c1) \end{smallmatrix} ||Cd_xHg_y\)

       (B)     \(Hg, Hg_2Ac_2| \)\(\begin{smallmatrix} CdAc_2(c) \\ HAc(c_1) \end{smallmatrix}||bridge||\)\(\begin{smallmatrix} NaAc(2c) \\HAc((c_1) \end{smallmatrix} |Hg_2Ac_2, Hg\)

  and     (C)     \(Hg, Hg_2Ac_2| CdAc_2(c)HAc(c_1)|Cd_xHg_y.\)

The constants for the first stage of dissociation, CdAc\(\rightleftharpoons\) CdAc⁺+Ac^- is 1.0 X 10^-1 and that of the second

stage,  CdAc⁺ \(\rightleftharpoons\) Cd⁺⁺+ Ac^- is 1.7 x 10^-2. These have been calculated from the study of the cells 'A' and

'II' on some assumptions. The study of the cell 'C' justifies these assumptions.
