Chlorides
First of all test pH value of Mud, If it shows alkaline then neutralized by using phenolphthalein indicator with Sulfuric Acid. Then titrated with standard silver nitrate solution, using potassium chromate as indicator. The results are reported as parts per million chloride ion, although actually measured in terms of mg Cl ion per 1000 cm3 of filtrate. To determine the chloride content of an oil mud, the sample is diluted with isopropyl alcohol and then mixed with distilled water, neutralized to the phenolphthalein end point, and then titrated in the usual way.
The end point is difficult to detect using the silver nitrate method, and the results depend to some extent on the operator. Titrating with mercuric nitrate, using bromophenol blue as an indicator, is an alternative. The method gives a much sharper end point, which is particularly advantageous when titrating whole mud, especially oil muds.
We are manufacturer of Mercuric Nitrate in LR/AR/ACS grade. Mercuric Nitrate is being used as an Laboratory Reagent and various organic synthesis for Mercuration.
Mercuric Nitrate reacts with Chloride ions to form soluble, mostly undissociated Mercuric Chloride, and is commonly used in the determination of Chloride. Diphenylcarbazone (DPC) is used as the indicator:
excess Hg2+ + DPC → [HgDPC]2+ (blue-violet complex)
While the Mercuric Nitrate titrimetric method for determining Chloride is the official or approved method in some States, the use of the less toxic and environmentally less harmful Silver Nitrate is a more popular method of Chloride determination, whenever the lower detection limit of the Mercuric Nitrate method is not required.
Mercuric Nitrate solutions can be standardized with a standard Chloride solution, using Diphenylcarbazone (DPC) as an indicator. A pH indicator, such as Bromophenol Blue or Xylene Cyanol FF, can be added to the Diphenylcarbazone Indicator to show if the pH is in the proper range for the titration.
Mercuric Nitrate solutions can also be standardized with standard Ammonium or Potassium Thiocyanate solution, using Ferric Alum as the indicator:
Hg2+ + 2 SCN- → Hg(SCN)2 (white precipitate)
excess SCN- + Fe3+ → [FeSCN]2+ (red complex)
