Equipment : pH 


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.
