What is the hydroxide ion concentration of a solution containing 1N NaOH?

Answer 1

1. Weigh 4 g NaOH.

2. Put this NaOH in a 1 L volumetric flask.

3. Add slowly 100 mL distilled water and stir.

4. Put the flask in a thermostat at 20 0C and maintain for 1 hour.

5. Add distilled water up to the mark. Stir vigorously.

6. Standardize the solution by titration with oxalic acid, potassium hydrogen phtalate, etc.

7. Transfer the solution in a bottle and apply a label (date, name of the operator, name of the solution, normality).

Answer 2

1. Weigh 40 g NaOH.
2. Put this NaOH in a dry 1 L volumetric flask.
3. Add slowly 900 mL distilled water and stir until dissolved.
4. Put the flask in a thermostat at 20 0C and maintain for 1 hour.
5. Add distilled water up to the 1 L-mark and mix the closed bottle.
6. Standardize the solution by titration with oxalic acid, potassium hydrogen phtalate, etc.

Answer 3

molecular weight of NaOH is 40. so 1N NaOH= 40g/L

Answer 4

40 g of NaOH dissolved in distilled water and make up to 1 litre gives 1 N.

Answer 5

It is sodium hydroxide with 1 mole per litre

Answer 6

Take 40 grams (= 1 mole) NaOH, carefully add it to approx. 0.9 L water while stirring, then fill up to 1.0 Liter to get 1M = 1N NaOH sol'n.

Answer 7

17 g/kg OH
