2NaCl + 2 H_{2}O = NaCl + NaO, ClO + 4H.

In operating in this manner we shall have the advantage that results
from the nascent body through the electrical double decomposition of the
chloride of sodium and water, which puts the chlorine, the metal, the
hydrogen, and the oxygen simultaneously in presence. The chlorine and
oxygen will combine their action to decolorize the textile material.

While starting from this idea, it will nevertheless be preferable to
adopt Naudin & Schneider's arrangement.

The apparatus consists of a hermetically closed electrolyzer, A,
into the lower part of which enters the electrodes, E and F, of any
electrical machine whatever. The receptacle, A, is provided with a
safety-tube, T, that issues from its upper part and communicates with
a reservoir, B. A second tube, D, forms a communication between the
electrolyzer and the vessel, C. The liquid contained in this latter is
sucked up by a pump, P, and forced to the lower part of the vessel, A,
by means of the tubes, G and H.

The apparatus operates as follows:

The closed vessel, C, in which the material to be bleached is put, is
filled, as is also the electrolyzer, with a solution of chloride of
sodium. This solution is then submitted to the action of an electric
current, when, as a consequence of the chemical decomposition of
the chloride and the water, the elements in a nascent state form
hypochlorite of soda. When the partial or total conversion of the liquid
has been effected (this being ascertained by chlorometric tests), the
