Dicamphorylarsinic oxychloride, (CioHi50)2AsO.(U, results when potassium dicamphorylarsinate reacts with phospliorus pentachloridc. It crystallises from chloroform and benzene in colourless < rystals, M.pt. 158° C. It rapidly decomposes in air, and its specilic rotation in dry chloroform has the value [a]j)+106°. 

In general, it can be concluded that the main reason for the evolution of the salt framework during freeze-drying is the complicated diffusion of water vapor within the product particles caused by the specific micromorphology of frozen solutions. Such complications take place during ice sublimation from all cryoc-rystallization products and they can be considered as one of the main features of their freeze-drying processes.

Carbolic acid is a white substance in the crystalline form. The 5% olution is most often used. It is made by dissolving this amount of rystals in water. Liquefied carbolic acid is made by adding 1 part of rater to 9 parts of the crystals. 

In some cases, there is evidence of multiple solid-solid transitions, either crystal-probably formation of plastic crystal phases - indicated by solid-solid transitions that consume a large fraction of the enthalpy of melting [21], which also leads to low energy melting transitions. The overall enthalpy of the salt can be dispersed into a large number of fiuxional modes (vibration and rotation) of the organic cation, rather than into enthalpy of fusion. Thus, energetically, crystallization is often not overly favored.

For metals with a great difference between the p.z.c. values of the faces, it is necessary to keep in mind the specific dependence of the p.z.c. values of the singlevalue typical for (110) and higher-index faces, at a relatively small change of the crystallographic orientation. Therefore, one cannot exclude an alternative interpretation of the above-mentioned experimental observations for such PC electrodes. Namely, one can envisage that their surfaces do not contain perfect (111) or (100) faces but only perturbed ones. Their p.z.c. values are not much different from those for the (110) or (210) faces.

Quantitative understanding of the electrochemical deposition and dissolution of metals became possible since Clavilier established the technique to prepare a well-defined surface of a platinum singleatomic force microscopy (AFM) [11] soon after, made the study on the surface structure of the electrode in situ possible at atomic resolution. The surface structures of many noble metal singlecrystal electrodes, such as Aa h1d) [12,13], Pt(hki)[14, 15], Pd(hW) [16], Rh(Hkf) [17], and Ir(hkl) [18], have been investigated by STM under electrochemical control at atomic resolution. Reality involves understanding the relationship between the electrochemical behavior and the surface structure of these electrodes.
