Question

to determine sulphate concentration of a given water sample by turbidimetric method​

Answer 1

Answer:

Procedure

Measure 100 mL or suitable portion of the sample into a 250 mL Erlenmeyer flask.

Add 5 mL of conditioning reagent and mix it by placing on a magnetic stirrer.

Add a spoonful of barium chloride crystals and begin timing immediately.

Stir at constant speed exactly for one minute.

Answer 2

Answer:

In the turbidimetric determination, the sulphate ions present in the sample are converted into a suspension of barium sulphate which is then determined turbidimetrically. You would be using a spectrophotometer to determine the turbidity of a solution.
