Undesirable polarization can be suppressed by vigorous agitation of the electrolyte, or when agitation is impractical ( such as in a stationary battery ) with a depolarizer.
12.
In the battery industry, the term " depolarizer " has been used to denote a substance used in a primary cell to prevent buildup of hydrogen gas bubbles.
13.
The term " depolarizer " can be considered as outdated or misleading, since it is based on the concept of " polarization " which is hardly realistic in many cases.
14.
As with the Cornu depolarizer, there is some separation of the output as a function of polarization, as well as some beam deviation due to the imperfect match in refractive index between quartz and silica.
15.
Because each half of the optic is a wedge, and the two halves do not have exactly the same refractive index ( for a particular polarization ), the depolarizer is effectively very slightly wedged ( optically ).
16.
The letter " L " indicates the electrochemical system used : a zinc negative electrode, manganese dioxide depolarizer and positive electrode, and an alkaline electrolyte . " R44 " indicates a cylindrical ( " round " ) cell 11.4?.2 mm diameter and 5.2?.2 mm height.
17.
A "'depolarizer "'or "'depolariser "', in electrochemistry, according to an IUPAC definition, is a synonym of "'electroactive substance "', i . e ., a substance which changes its oxidation state, or partakes in a formation or breaking of chemical bonds, in a charge-transfer step of an electrochemical reaction.

Where k is a constant which includes ? and the density of mercury, and with the Faraday constant ( F ) has been evaluated at 708 for max current and 607 for average current, D is the diffusion coefficient of the depolarizer in the medium ( cm2 / s ), n is the number of electrons exchanged in the electrode reaction, m is the mass flow rate of Hg through the capillary ( mg / sec ), and t is the drop lifetime in seconds, and c is depolarizer concentration in mol / cm3.
