Reagents: Solid sodium bicarbonate, 0.00025N KI+I2 solution, Starch indicator
Procedure:
. Preparing 20 ml of saturated solution of sodium bicarbonate with the sample solution.
. 2.5 ml of the above solution was taken in a test tube with a calibrated Pasteur pipette.
. Adding 1 drop of starch indicator to the tube and stir well.
. Adding KI + I2 solution drop wise with another pipette till a blue colour of the solution appears.
. Count the number of drops of KI + I2 solution used.
Calculation:
Volume of KI + I2 solution = no. of drops x value of pipette= V1 Normality of KI + I2 solution = N1
Volume of water = 2.5 mL = V2
Amount of arsenic (mg/L) = V1 x N1 x 37.5 x 1000/V2
Result: The amount of arsenic in water is ________ mg/L.
Note: The iodine solution may change in strength if it is not used for a long time.
Just add two crystals of solid iodine just before use. ( This test can detect upto 5 x 10-6 ppm of arsenic)
