Standardization
Easychemistry
Primary standard for standardizing NaOH solution is:
Select the correct option:
Solution
Incorrect! Answer:
Oxalic acid
A Primary Standard is a substance that is very pure, stable, and can be weighed accurately to make a solution of exactly known concentration.
- NaOH is not a primary standard because it is hygroscopic (absorbs moisture) and reacts with CO2 from the air.
- Oxalic acid (H2C2O4⋅2H2O) is used as a primary standard. It is a solid, does not change mass in air, and has high equivalence weight, making it ideal for standardizing NaOH solutions via simple acid-base titration.
