Question

Find the concentration of the solution which consists of 50 g of NaOH in 100 mL of water. *
25 %
50 %
75%
33%

Answer 1

Answer:

How can you prepare a 10% Sodium Hydroxide (NaOH) solution?

For the preparation of 10% Sodium Hydroxide (NaOH) solution follow that steps

(% age = [(required mass)/total mass]x100

10 % = [required mass/ 100]x100

Percent mean in 100 so, total mass is 100

So,

required mass = 10 g)

Dissolve 10.0g of NaOH pellets in small quantity of deionised water in a beaker.

When cooled, bring the final volume to 100ml.

The dissolution of sodium hydroxide in water is exothermic reaction, stirring should be commence immediately upon adding of water to avoid localized hot spots in beaker.
