Preparation and standardization of 0.05 M Silver Nitrate BP Volumetric Solution
Dissolve 8.5 g of Silver nitrate in sufficient carbon dioxide free water to produce 1000 ml
Dissolve 0.05 gm of Sodium chloride in 30 ml of water and titrate with Silver nitrate solution potentiometrically.
Each ml of 0.05 M Silver nitrate VS is equivalent to 2.922 mg of NaCl.
Molarity (M) = [0.05 x weight of Sodium chloride (in g)]/ [Titration reading (in ml) x 0.002922]
Limit: 0.05 M ± 5 % (0.0475 M – 0.0525 M)
3. STORAGE CONDITION:
Store in glass-stoppered bottles, protected from light.
