Volta, Alessandro galvanic cells

Italian physicist Alessandro Volta demonstrates the galvanic cell, also known as the voltaic cell. 

In addition, this review has been prepared to promote the term voltaic cell in honor of Alessandro Volta, the inventor of the pile, i.e., an electrochemical generator of electricity. Up to now this name has been used in only a few papers. This term is a logical analogue to the term galvanic cell, particularly in discussions of Volta potential and Gal-vani potential concepts. 

Galvanic cells are named after the Italian doctor Luigi Galvani (1737-1798), who generated electricity using two metals. These cells are also called voltaic cells, after the Italian physicist Count Alessandro Volta (1745-1827), who built the first chemical batteries. 

Here we investigate some of the properties of galvanic cells, cells used to produce an electric potential. Luigi Galvani discovered the first such cell by accident in 1791. Following Galvani s discovery, Alessandro Volta developed a practical cell in 1800, and it was Volta s cell that led to the work of Davy and Faraday. 

The name galvanic cell honors Luigi Calvani (1737-1798), an Italian scientist generally credited with the discovery of electricity. These cells are sometimes called voltaic cells after Alessandro Volta (1745-1827), another Italian, who first constructed cells of this type around 1800. 

The experimental apparatus for generating electricity through the use of a spontaneous reaction is called a galvanic cell or voltaic cell, after the Italian scientists Luigi Galvani and Alessandro Volta, who constructed early versions of the device. Figure 19.1 shows the essential components of a galvanic cell. A zinc bar is immersed... 

Galvanic cells are named for Luigi Galvan , 1737-1798, an Italian anatomist who showed that electricity caused frog muscles to contract and that dissimilar metals In contact with the muscle tissue could produce an electric current They are also called voltaic cells after Alessandro Volta. 

It comes as logical consequence of what has been said in the previous section and in Table 13.2 that if the different metals are put in the same solution they originate a bimetallic galvanic cell or voltaic pile from the names of the Italian philosopher, physicist and physician Luigi Galvani who first discover it in 1780 and the Italian philosopher and physicist Alessandro Volta who farther investigate it in 1800 and... 

The dual aspect of the electrochemical cell—galvanic or electrolytic—was recognized shortly after the cell s discovery in 1800 by Alessandro Volta. Volta constructed a battery of cells consisting of a number of plates of silver and zinc that were separated from one another by porous strips of paper saturated with a salt solution. By 1807, Sir Humphry Davy had prepared elemental sodium and potassium by using a battery to electrolyze their respective hydroxides. But, the underlying scientific basis of the electrochemical cell was not understood. Michael Faraday s research showed a direct quantitative relationship between the amounts of substances that react at the cathode and the anode and the total electric charge that passes through the cell. This observation is the substance of Faraday s laws, which we state as follows ...
