Preparation and Standardization of 0.1 Normal Silver
nitrate Solution
0.1 Normal Silver nitrate (AgNO3) Solution Preparation
¨ To prepare 0.1 Normal solution of silver
nitrate (AgNO3) take 17 gram of silver nitrate in sufficient carbon-dioxide
free water with proper stirring to dissolve.
¨ Make the volume up to 1000 ml with
carbon-dioxide free water.
¨ Formula used
¨ Mass in gram
= Normality x gram equivalent weight x
required volume
1000
¨ Mass in gram
= 0.1 x 169.87 x
1000 = 16.98 gram
1000
Standardization
¨ Accurately weigh about 50mg of reagent grade
Sodium chloride (NaCl).
¨ Previously dried at 110◦C for 2 hours in an
oven and cooled in a desiccator.
¨ Transfer it gently to a 150 ml conical flask
and dissolve in 5 ml water.
¨ Add 2.5 ml Acetic acid and 25 ml of methanol.
¨ Now add about 0.5ml Eosin Y solution as
indicator.
¨ Titrate with 0.1 Normal Silver nitrate (AgNO3)
solution with constant stirring.
¨ Calculate Normality as follow
¨ Normality
= weight of sodium chloride taken(mg)
molecular weight of sodium
chloride x ml of 0.1 M AgNO3 used
¨ Normality
= weight of sodium chloride taken(mg)
58.44 X ml of 0.1 M AgNO3 used
