The accuracy of a measure is demonstrated by comparing it with a measure that has been demonstrated to be valid. In other words, correlations with other measures that have known validity. For this to work you must know that the criterion has been measured well.
Animation of a strong acid/strong base neutralization titration (using phenolphthalein). The equivalence point is marked in red. In chemistry, neutralization (US spelling) or neutralisation (UK spelling), is a chemical reaction in which an acid and a base react quantitatively with each other.cetic acid is an example of a weak acid. The pH of the neutralized solution is not close to 7, as with a strong acid, but depends on the acid dissociation constant (pK a)of the acid. The pH at the end-point or equivalence point in a titration may be easily calculated.
neutralization, neutralisation, neutralization reaction, neutralisation reaction(noun) a chemical reaction in which an acid and a base interact with the formation of a salt; with strong acids and bases the essential reaction is the combination of hydrogen ions with hydroxyl ions to form water.
