  Electrochemical process for producing chloric acid-alkali metal chlorate mixtures - Patent 5223103
A process for producing chlorine dioxide from an aqueous solution of chloric acid and alkali metal chlorate which is prouced in a electrolytic cell having an anode compartment, a cathode compartment and at least one ion exchange compartment between the anode and cathode compartments.
Where a non-oxidizable acid solution is used as an anolyte, the concentration of the anolyte is preferably selected to match the osmotic concentration characteristic of the alkali metal chlorate solution fed to the ion exchange compartment to minimize water exchange between the anode compartment and the ion exchange compartment.
Further, the chloric acid --alkali metal chlorate solutions produced are substantially free of chloride, sulfate, phosphate, or other anionic groups which are present when an alkali metal chlorate is acidified with mineral or other acids used in the generation of chlorine dioxide.

  U.S. Patent: 5174868 - Chlorine dioxide generation from chloric acid - December 29, 1992   (Site not responding. Last check: 2007-11-03)
Chloric acid for the process is produced electrolytically from an aqueous solution of the deadload sodium chlorate and make-up quantities of sodium chlorate.
Chlorine dioxide generated in the generator 12 from the aqueous acid reaction medium is vented from the chlorine dioxide generator 12 by line 18 in admixture with steam and is processed to form an aqueous solution of chlorine dioxide for subsequent use, such as in pulp mill bleaching.
An aqueous solution of 5.1 M sodium chlorate and 1.44 N chloric acid was fed to the reaction medium at a flow rate of approximately 50 mL/min while methanol was fed to the generator at a flow rate of approximately 4.6 mL/min.

 Chlorates - LoveToKnow 1911
CHLORATES, the metallic salts of chloric acid; they are all solids, soluble in water, the least soluble being the potassium salt.
They may be prepared by dissolving or suspending a metallic oxide or hydroxide in water and saturating the solution with chlorine; by double decomposition; or by neutralizing a solution of chloric acid by a metallic oxide, hydroxide or carbonate.
This releases chloric acid, which, being an extremely powerful antiseptic, kills the bacteria to which the ulcers are due.

 Method to reduce the potential salt cake content of chlorine dioxide generator spent acids - Patent 4578261
In the Solvay process, acid is consumed in the initial generation of chloric acid, and additional acid is consumed for the generation of hydrochloric acid, as in the case with the R-2 and R-3 processes.
The acid recovery process which comprises an added chemical plant to the existing chlorine dioxide plant, represents the only true method known wherein all the sulphuric acid is recovered in the Mathieson process for eventual recycle back into the primary generator.
Sulphuric acid at 93-96% concentration is fed through line 14 and is used solely for startup in a Mathieson process generator 2 and at much reduced levels of concentration in Solvay and chloride reduction processes.

 ACID - Definition
Of or pertaining to an acid; as, acid reaction.
When the hydrogen of an acid is replaced by a positive element or radical, a salt is formed, and hence acids are sometimes named as salts of hydrogen; as hydrogen nitrate for nitric acid, hydrogen sulphate for sulphuric acid, etc.
In the old chemistry the name acid was applied to the oxides of the negative or nonmetallic elements, now sometimes called anhydrides.

 the period 3 hydroxides
There are other acids (also containing -OH groups) formed by these elements, but these are the ones where the Period 3 element is in its highest oxidation state.
The main factor in determining the strength of the acid is how stable the anion (the negative ion) is once the hydrogen has been removed.
Phosphoric(V) acid is much weaker than sulphuric acid because it only has one phosphorus-oxygen double bond which it can use to help delocalise the charge on the ion formed by losing one hydrogen ion - so the charge on that ion is delocalised less effectively.

 Chemical Sciences: Acids and Bases: Intrinsic Strength is Related to Molecular Structure
The intrinsic strength of an acid or base is determined by the molecular structure of the acid or base and by the solvent in which it is acting.
Since every acid has a conjugate base, and the conjugate acid differs from its conjugate base only in that the acid has a single proton which the conjugate base does not, it is equally possible to compare acids with acids or bases with bases.
The strengthening of the acid (decreasing strength of the nitrogen-hydrogen bond) observed for the trimethyl substitution cannot be explained in this way, and may arise from a some difference in the interaction of water with this compound.

 Strong acid - Wikipedia, the free encyclopedia
This generally means that in aqueous solution at standard temperature and pressure, the concentration of hydronium ions is equal to the concentration of strong acid introduced to the solution.
While strong acids are generally assumed to be the most corrosive, this is not always true.
The difference separating the acid dissociation constants of strong acids from all other acids is so great that this is a reasonable demarcation.

In fact, many acids are simply substances in which one or more hydrogens has been added to the anions we talked about in the last chapter.
So writing a reaction between an acid and a base involves reacting the H from the acid with the OH from the base to form water, and the other product is a salt, which consists of the metal (from the basic metal hydroxide) and the anion from the acid.
Sometimes the same substance can be acting as both an acid and a base at the same time, which is the case in the very slight dissociation of water we discussed earlier.
