what is the principle and procedure involved in the assay or standardization of silver nitrate?
Answers
Answer:
Silver Nitrate Solution 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.
Silver Nitrate Solution 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 the molarity of solution by the following formula :
M = NaCl in mg/AgNO3 in ml x 58.44

Hope this helps you buddy ♡
