Popular passages
Page 14 - aqueous solution of a metallic salt, for instance, copper, being subjected to a voltaic current, has hydrogen presented at the cathode, and oxygen at the anode. But at the same time this change is taking place, oxide of copper is passing to the cathode and sulphuric acid to the anode. The hydrogen seizes upon the oxygen of the oxide of copper, and forms water, whilst
Page 14 - we find a body at the pole of a battery, it is by no means certain that it has passed by direct decomposition of the Voltaic current ; because, if the compound of which it formed a part was dissolved in water, the elements of the latter being set free, often act in an important way to form new combinations, which result from the secondary effects ; thus
Page 8 - to the platinized silver, a very different effect is produced. With the apparatus thus arranged, the spark that results from the contact of the wire with the steel plate is accompanied
Page 14 - metallic copper is thrown down on the electrode or pole, not by direct voltaic action,
Page 15 - not by direct voltaic action, but as a secondary effect attributable to the hydrogen,
