Determination of kf factor

Operate the KF titrator using suitable operating procedure. A commercially available, stabilized solution of Karl Fischer type reagent may be used. Commercially available reagents containing solvents or bases other than pyridine or alcohols other than methanol may be used also.

The diluted Reagent called for in some monographs should be diluted as directed by the individual testing procedure. Either methanol or other suitable solvent, such as ethylene glycol monomethyl ether, may be used as the diluent.

The same solution shall be standardized. Standardization of KF Reagent by Water : Unless otherwise specified, transfer 35 to 40 mL of methanol or other suitable solvent to the titration vessel.
Neutralise the solvent with KF reagent. Weigh accurately between 25 to 250mg of water, transfer it into the titration vessel. Titer the content with Karl Fischer reagent to end point to the electrometric or visual endpoint. Perform the above titration in duplicate. Calculate the Factor using the formula
Neutralise, ethylene glycol monomethyl ether, pyridine, alcohols

Preparation of barium chloride solution

Pour about 75 ml of Distilled water into a 250 ml capacity beaker. Weigh 10.0 grams of Barium Chloride LR and transfer slowly, into above said beaker, through it‘s side walls, while gentle mixing, by using a glass rod. Transfer prepared solution into a 100 ml volumetric flask, by using a glass funnel. Rinse the beaker and funnel with few ml of Distilled water, and allow to add into the contents of volumetric flask. Make up the volumetric flask to mark with Distilled water, remove the funnel, keep the lid to close the volumetric flask and shake gently to mix the solution. Transfer the prepared solution into a suitable container and label with all necessary details. The resultant solution is having the concentration of 10.0% w/v. Barium Chloride , Distilled water, Glass rod, Glass funnel, Calibrated Analytical Balance

Procedure for Collection Transfer and Disposal of Scrap

Scrap essentially consists of metal scrap (MS, SS, Aluminum etc.) arising from engineering fabrication work and fiber drums, HDPE drums, carboys and polythene covers etc. from raw material packaging.Collection of Scrap: Scrap collection points are identified at the following locations. Scrap arising are placed in the above collection points. Scrap from these points are periodically shifted to scrap disposal yard outside Scrap segregation is done at disposal yard – namely as MS, SS, Aluminum, HDPE drums, carboys, fiber drums, polyethylene bags and cardboard cartons. Scrap is disposed from the disposal yard. Collection , Transfer, Disposal of Scrap, segregation

PREPARATION OF SILVER NITRATE SOLUTION (5 percent )

Pour about 75 ml of Distilled water into a 250 ml capacity beaker. Weigh 5.0 grams of Silver Nitrate LR and transfer slowly, into above-said beaker, through its sidewalls, while gentle mixing by using a glass rod. Transfer prepared solution into a 100 ml volumetric flask, by using a glass funnel. Rinse the beaker and funnel with few ml of Distilled water, and allow to add into the contents of volumetric flask. Make up the volumetric flask to mark with Distilled water, remove the funnel, keep the lid to close the volumetric flask and shake gently to mix the solution. Transfer the prepared solution into a suitable container and label with all necessary details. The resultant solution is having the concentration of 5.0% w/v. Silver Nitrate , Glass funnel, Beaker, Distilled water , Glass rod
