Procedure

Experimental PartSome of the reagents and apparatus used for the estimation of sulphate ions using turbidimetry are:

1.Potassium Sulphate2.Sodium Chloride3.Barium Chloride4.Glycerol5.Pure Alcohol(Ethanol)6.Nephelometer/Turbidimeter

Procedure1.Preparation of Standard Sulphate Solution:

dissolve 0.4535g of dry potassium sulphate in distilled water and make the volume to 250 ml.

Then this solution has the concentration of 1.0mg/ml2.Preparation of Barium Chloride Solution:

Pass the finely powdered crystals of barium chloride weighing 5g in the 100ml of distilled water3.Preparation of Conditioning Reagent:

50ml glycerol+30ml conc.HCL+300ml distilled water+100mlof 95%ethanol+75g of NaCl

1.Take seven 50ml volumetric flasks and label them accordingly, and the first one is for the blank solution preparation2.Transfer 1,2,3,4 and 5 of the standard sulphate solution in the flask number 2,3,4,5 and 63.To each flask add 30ml of conditioning reagent solution4.Add 10ml of barium chloride solution to each flask and make the volume to 50ml. Allow flask to stand for 5 minutes5.The flask marked 1 will have allasunder 3 and 4 but except 26.Use the flask labelled as 7 for the unknown solution.
