    10% of NaOH solution simply means that 10 gram of NaOH is present in 100 units of solution. It is a w/v% where 10gram of NaOH is present in 100ml of solution, i.e., in 90ml of distilled water.

    Let us understand its preparation through an experiment.

    To perform the experiment, you will need the following materials-

    1. A measuring cylinder

    2. A flask

    3. a glass rod

    4. distilled water


    1. Weigh out 10g of NaOH using 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 to 90ml by adding distilled water.

    5. Stir the solution again


    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 little amount of water is added first that dissolves the NaOH.


    10% of NaOH was prepared.

    I hope this helps.
