That is solution is 1N NaOH when 40g NaOH is dissolved in 1L water. Here, molarity and normality will be same. For our purpose, weigh 20g of NaOH and dissolve it in 500ml water. At this point, the solution is 1N NaOH. Dilute this solution to 1000ml. Stir well. You have 0.5N NaOH solution. Done.
Before starting how to prepare 0.1M NaOH solution, first of all need to understand, what is Molar Solution? What is Molar Solution?:
There are two ways to prepare 0.1M Sodium Hydroxide (NaOH) solution.
Procedure for Preparation of 0.1M NaOH Solution by using sodium hydroxide pellets
Procedure for Preparation of 0.1M NaOH Solution from 1M NaOH0.1M NaOH solution is 10 times less concentrated than 1M NaOH solution.
These are the two ways how to prepare 0.1M NaOH solution. But to get the exact Molarity of the solution, titration needs to perform. I hope you understand how to prepare 0.1M NaOH solution.
