Now, we know that the number of electrochemical equivalents electrolysed is proportional to the whole amount of electricity which passed through the circuit, and the product of this by the electromotive force of the battery is the work done by the latter, so that in this case also Joule showed that the heat generated was proportional to the work done.
The electrochemical equivalent of any other substance, whether element or compound, may be found by multiplying its chemical equivalent by I 036X Io-5.
The subject was pursued by Thomson and the Cambridge physicists with great mathematical and experimental ability, and finally the conclusion was reached that in a high vacuum tube the electric charge is carried by particles which have a mass only a fraction, as above mentioned, of that of the hydrogen atom, but which carry a charge equal to the unit electric charge of the hydrogen ion as found by electrochemical researches.
He followed up the early work of the British Association Committee on electrical units by a fresh determination of the ohm in absolute measure, and in conjunction with other work on the electrochemical equivalent of silver and the absolute electromotive force of the Clark cell may be said to have placed exact electrical measurement on a new basis.
Lincei, 1905 (iv.), 14, pp. I, 23, 104), who, by a determination of the electrochemical equivalent of the element, arrived at the value 127.61 A.
Similarly, the heat which accompanies the dissolution of one electrochemical unit of copper is 3.00 calories.
In fact, long previously to Faraday's electrochemical researches, Sir H.
In this way the development of the electrochemical industry is in a marked degree altering the distribution of trade throughout the world.
Hence for the electrochemical unit of zinc or 0.003388 gramme, the thermal evolution is 5.66 calories.
He also investigated the diamagnetic and paramagnetic properties of substances; and was keenly interested in the phenomena of electrochemical decomposition, accumulating much evidence in favour of Faraday's law and proposing a modified statement of it which was intended to cover certain apparent exceptions.
