The substances present in the solution being titrated when it has been titrated halfway to the equivalence point have to be stated. The relation of pH of the half-titrated solution to the p K a for the weak acid is to be stated. Concept introduction: pH of a solution is the value of negative logarithm of the concentration of hydrogen ions in a solution. An acidic solution has a pH below 7 , a basic solution has a pH more than 7 and a neutral solution has a pH equal to 7 . The point in a titration where chemically equivalent quantities of the acid and the base have been mixed together is known as the equivalence point of the titration.
