preparation of 0.1N NaOH Solution

Normality (N):- Normality is the number of gram equivalents of solute/liter of solution.

Molecular Weight Of NaOH:- 40g/mol

0.1Normality= 4g/L of NaOH

Prepare 0.1N NaOH (1 Liter)

1. Accurately Weigh 4gm Of NaOH pellets
2. Add the NaOH Pellets to approx 700ml of distilled water and Mix in a volumetric Flask.
3. Add Distilled water to make up the Volume to 1 Liter.

Note Storage:- Store in Tightly pack plastic bottle.

Titration 0.1N NaOH

• Dry PHP (Potassium Hydrogen Phthalate) Oven in 45 minutes.
• Cool
• 0.2gm in 250ml Conical Flask.
• 20ml Distilled Water mixing 5 minutes.
• Phenolphthalein Indicator 2-3 drops.
• Titrate with NaOH 0.1N
• End Point Pink Appear

Record- Note the Volume Of NaOH use from the Burette.
