Preparation and Standardization of 0.1 M Silver Nitrate


Learn how to prepare and standardize the 0.1 M Silver Nitrate solution using Sodium Chloride and Eosin Y indicator.

Preparation:

•  Take about 100 ml of water in a cleaned and dried 1000 ml volumetric flask.
•  Add about 17 gm of Silver Nitrate with continues stirring.
•  Add more about 700 ml of distilled water, mix.
 Make up the volume 1000 ml with water. Mix solution thoroughly.
•  Keep the solution for at least one hour and then carry out the standardization.

Standardization:

•  Transfer about 50 mg, accurately weighed, of reagent-grade sodium chloride, previously dried at 110° for 2 hours, to a 150-ml conical flask.
•  Dissolve in 5 ml of distilled water. 
•  Add 2.5 ml of acetic acid, 25 ml of methanol, and about 0.25 ml of Eosin Y indicator.
•  Stir, preferably with a magnetic stirrer.
•  Titrate with the silver nitrate solution.
•  Calculate molarity of solution by following formula:

                NaCl in mg
M = ---------------------------
         AgNO3 in ml  x 58.44
