Nitric Acid Solution Preparation
- Dilute 63 ml of nitric acid with sufficient water to produce 1000 ml.
- Standardize the solution in the following manner.
Nitric Acid Solution Standardization
- Dissolve 2 g of anhydrous sodium carbonate in 50 ml of water.
- Titrate with the nitric acid solution using methyl orange solution as indicator until the solution becomes reddish yellow.
- Boil for 2 minutes, cool and continue the titration until the reddish-yellow color is restored.
- 1 ml of 1 M nitric acid is equivalent to 0.053 g of Na2CO3.
- Calculate the molarity of solution by the following formula:
Na2CO3 in mg
M = --------------------------
HNO3 in ml x 53
