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 = ---------------------------
AgNO3 in ml x 58.44
Is there other way of standardizing Silver Nitrate?
ReplyDeleteWhat is the problem with this method.
DeleteSir this method good but factor limit 0.95 to 1.05 na
