The electromotive force of a galvanic cell,emical reaction can proceed in the system. It seems to be a reasonable starting point to describe a system in which two different electrolyte solutions are placed in contact with another. The remaining two boundaries are formed from solid materials and the loop is closed by some inert metal which dodelusion 发表于 2025-3-28 21:41:15
Galvanic cells containing only one type of anion (or correspondingly, one type of cation), and only one anionic constituent. As a first example, we choose the NaCl + KCl system. The galvanic cell with an electrolyte containing two different anionic species and only one cationic constituent should be treated in an analogous way.厌烦 发表于 2025-3-28 23:18:46
The salt bridge, set-up is simple. The two half cells from which the galvanic cell is to be constructed, are not brought into direct contact, rather they are connected via an electrolyte phase which in most cases consists of a concentrated KCl solution. Experimental details need not be given here. The conventional直言不讳 发表于 2025-3-29 05:51:20
Membrane potentials,nt Na is formed but which does not contain the constituent Cl. Then, in the left-hand and right-hand compartments we have Cl. electrodes or also Ag/AgCl — or calomel-electrodes —. Thus the system has the construction scheme as shown in Fig.42.ligature 发表于 2025-3-29 08:24:03

The corresponding equations for polyvalent electrolytes will only occasionally be added. Their derivation is straightforward in all cases.火光在摇曳 发表于 2025-3-29 15:49:27

It is the purpose of this treatment to describe the interconnection between the electric current in a composite thermodynamic system and the rate of production of a certain substance on the one side, the rate of deple tion of another substance on the o好色 发表于 2025-3-29 20:14:03

György Inzelt,Andrzej Lewenstam,Fritz Scholzshaped in a particular way in which a chemical reaction proceeds. In the following pages we shall repeatedly give this schematic representation of a galvanic cell as a “reaction vessel”. This is in contrast to the abbreviated form of representation which is commonly used in conventional treatments and also in the heading of this section.frugal 发表于 2025-3-30 07:45:29
