Polyguard’s RG-2400 does more than create a mineral lattice into
and onto metal surfaces. If moisture, in vapor or liquid form, passes
through the gel, RG-2400 will elevate the pH to 10.4 or higher.
Water, with an elevated pH of 10.4 or higher will not act as an electrolyte
when in contact with a metal surface, so corrosion cannot occur.
An ion is an electrically charged chemical particle in solution. And
in water the electrically charged particle is the Hydrogen ion. The counterpart
of this ion in an alkaline water solution is the Hydroxyl ion, the degree
of presence which determines the alkalinity of the solution.
Oxygen is the one chemical ion which is present in all alkalis, acids,
water, and in air, and it is needed to maintain the chemical reaction
known as oxidation. Two examples of this are: the rusting of iron or
steel, and the white corrosion products on zinc plated surfaces. Also,
Oxygen is the cause of breakdown or decomposition of certain chemical
products.
The hydrogen ion
concentration was found to vary over fourteen powers of 10. A change
of one pH unit changes the hydrogen
ion concentration
by a factor of ten. For example, a solution with a pH of 1 has 10 times
more hydrogen ion concentration than a pH of 2; One hundred times more
hydrogen ion concentration than a pH of 3 and so forth. This means that
a solution with a pH of 1 has one million times more hydrogen ion concentration
than a pH of 7. To avoid dealing with these incredibly complex exponential,
scientists proposed a simplification. They converted the exponents -7,
0 and -14 to 7, 0 and 14 respectively. Subsequently, the pH scale was
established ranging from 0 to 14 with the mid-point of 7 indicating neutrality.
Therefore, the scale of ordinary pH values extends from 0 to 14. The
pH of a neutral solution is 7. Thus the range of acid pH values extends
from 0 to 7, and that of alkaline values from 7 to 14 (thanks to
Roger McFadden).
