How can you prepare a 10% Sodium Hydroxide (NaOH) Solution?
How Can You Make A 10% Sodium Hydroxide Solution?
10% of NaOH solution simply means that 10 grams of NaOH are present in 100 units of solution. It is a w/v% where 10 grams of NaOH is present in 100ml of solution, i.e., in 90ml of distilled water.
Let us understand its preparation through an experiment.
To experiment, you will need the following materials-
1. A measuring cylinder
2. A flask
3. A glass rod
4. Distilled water
Procedure:
1. Weigh out 10g of NaOH using a digital balance or any weighing machine you have.
2. Transfer it into a flask and add a little distilled water to it
3. Stir the mixture using a glass rod until a homogenous, clear solution is formed
4. Now make the volume 90ml by adding distilled water.
5. Stir the solution again
Precautions:
1. If you are using a digital balance, make sure it has been tared and is initially at zero
2. Don’t handle the salt directly- being hygroscopic, it might absorb the moisture from the fingers that can disturb its chemical ratio
3. The entire 90ml volume of water is not added to the salt, as it can lead to errors when 10g of NaOH gets dissolved in it. To get exact results, a small amount of water is added first to dissolve the NaOH.
Result:
10% of NaOH was prepared.
I hope this helps.
