How can you make 10N NaOH?

Answer 1

You need 400 g of solid NaOH dissolved in water and made up to exacly 1 liter in a volumetric flask.

For 1 L solution:

1. Weight 399,9711 g of NaOH per analysis with an analytical balance.

2. Put the NaOH in a clean and dry Berzelius beaker.

3. Add very slowly and by stirring 500 mL water distilled (deionized); avoid the superheating.

4. Transfer quantitatively this solution in a 1 L volumetric flask.

5. Put the flask in a thermostat at 20 0C.

6. Wait for the temperature stabilization of the flask with the solution.

7. Add slowly distilled (deionized) water to the mark.

8. Stir the volumetric flask.

9. Put on the flask a label with: name of the reagent, concentration, date, operator.

Answer 2

Dissolve 399,971 g NaOH in 1 L distilled water at 20 0C.

Answer 3

40 g of NaOH + 100 ml water
