Preparation of 0.1N Sodium Hydroxide (NaOH) Solution

Sodium Hydroxide (NaOH) is a Strong base. Use in Acid-Base titration and analysis.

To prepare 0.1N Sodium Hydroxide (NaOH) Solution.

Molecular Weight Of NaOH:- 40g/mol

0.1Normality= 4g/L of NaOH

Prepare 0.1N NaOH (1 Liter)

• Weigh 4gram of Sodium Hydroxide (NaOH) pellets.
• Add About 300-400mL Distilled Water with Clean Beaker.
• Stir until Sodium Hydroxide (NaOH) dissolve completely.
• Volume Make up to 1000mL mark.

Note Storage:- Store in Tightly pack plastic bottle.

Calculation Formula

N₁V₁ = N₂V₂
