How is nitric acid prepared?

Nitric Acid (1M) 

Molecular formula: HNO₃ 

Molecular weight: 63.01 

Preparation: Dilute 63 mL of nitric acid with sufficient water to produce 1000 mL. 

Standardization: Dissolve 2 g of anhydrous sodium carbonate in 50 mL of water and titrate with the nitric acid solution using methyl orange solution as an indicator until the solution becomes reddish yellow. Boil for 2 minutes, cool, and continue the titration until the reddish-yellow color is restored. 

Reactions: 

Na₂CO₃ + 2HNO₃ → 2NaNO₃ + H₂CO₃

H₂CO₃ → H₂O + CO₂↑

 Factor Calculation: 

2 moles of HNO₃ ≅ 1 mole of anhydrous sodium carbonate

2000 mL of 1M HNO₃ ≅ 105.99 g of Na₂CO₃

1 mL of 1 M HNO₃ ≅ 0.05299 g of Na₂CO₃
