Galvanic electricity

Electrolysis.—When a galvanic current of sufficient power passes through a compound liquid, or through a solution of a compound, capable of conducting the current, the compound is decomposed. The decomposition of a compound by this meana is called electrolysis, and the substance so decomposed is known, as the electrolyte. 

When compounds are subjected to electrolysis the constituent elements are not discharged throughout the mass, although the 

Residues of acids remaining after the removal of a number of hydrogen atoms equal to the basicity of the acid.

The discovery of galvanic electricity (i.e. electrical phenomena connected with the passage of electric current) by L. Galvani in 1786 occurred simultaneously with his study of a bioelectrochemical phenomenon which was the response of excitable tissue to an electric impulse. E. du Bois-Reymond found in 1849 that such electrical phenomena occur at the surface of the tissue, but it was not until almost half a century later that W. Ostwald demonstrated that the site of these processes are electrochemical semipermeable membranes. In the next decade, research on semipermeable membranes progressed in two directions—in the search for models of biological membranes and in the study of actual biological membranes.

In his textbook section, "Chemical Physics," William Allen Miller treated elasticity, cohesion, adhesion, light, heat, magnetism, static electricity, galvanic electricity, and thermoelectricity.

Early History of the Electromotive Series, The roots of the choice of hydrogen as the standard for electromotive force measurement ( ) may be traced to the decade of the 1790 s and the discoveries of that period which were to change the whole state of science. Allessandro Volta, as a result of a series of experiments on what was later to be called galvanic electricity, published, as early as 1792, a list of substances in an order such that "each is positive toward all which follow it and negative to all which precede. In a footnote to a report in Ostwald s Klassiker dated August 1796, Volta ) reported as follows ...
