		neutralization, chemical reaction, according to the Arrhenius theory of acids and bases, in which a water solution of acid is mixed with a water solution of base to form a salt and water; this reaction is complete only if the resulting solution has neither acidic nor basic properties.
		In a neutralization reaction in which either a weak acid or a weak base is used, only partial neutralization occurs.
		In a neutralization reaction in which both a weak acid and a weak base are used, complete neutralization can occur if the acid and the base are equally weak.

		Both a weak acid and a weak base are largely undissociated, and the neutralization reaction therefore involves proton transfer from the weak acid to the weak base.

	Patent 4806638: Neutralization of reaction mixtures obtained by Beckman rearrangement of cyclohexanone oxime (Site not responding. Last check: 2007-11-05)
		In this procedure, the neutralization may be effected with gaseous ammonia or ammonia in aqueous solution or together with ammonium sulfate mother liquor, and the ammonia can be combined with the ammonium sulfate solution either upstream of the neutralization stage or directly in the neutralization stage.
		In the neutralization with itroduction of gaseous ammonia through a plurality of nozzel orifices, it has been found that these orifices become blocked within a short time, and uniform feed of ammonia into the medium to be neutralized, and hence satisfactory neutralization of the said medium, are not ensured.
		It is an object of the present invention to provide a process for the neutralization of reaction mixtures from the Beckmann rearrangement reaction, in which gaseous ammonia is fed in during the neutralization without difficulties and uniform neutralization of the reaction mixture is ensured.

		In theory neutralization involves adding acid or base as required to achieve pH 7.
		When the colour of an indicator is used to test for neutralization, the final pH may differ from pH 7 depending upon the indicator used.
		It will also differ from pH 7 in reactions between strong acids and weak bases and weak acids and strong bases, because the salt formed will have acidic or basic properties respectively.

		A means for promoting the neutralization reaction between particulate calcium carbonate and ionized phosphate by adding a material formed by the reaction of particulate calcium carbonate and dilute hydrofluoric acid.
		It is known that the rate and extent of reaction between a given quantity of phosphate ion and a given quantity of particulate calcium carbonate is dependent on the physical capability of each phosphate ion to contact a calcium carbonate molecule in solution or at a surface.
		The efficiency of the reaction between phosphate ion and particulate calcium carbonate is impeded by the formation of the relatively insoluble tricalcium phosphate on the external surfaces of the calcium carbonate particle involved.
