 Determination of pH

Equipment : pH  meter


Reagent: Standard pH buffer solutions (pH 4.0 , 7.0 , 9.2)


Procedure: Standardise the pH meter with standard pH buffer solutions of pH closer to the expected pH value of the sample at 250C± 20C.

Immerse the electrode in the solution being examined maintained at 250C± 20C.  Shake the contents foe about one minute and note the constant reading.
