Because NaOH is hygroscopic, meaning it absorbs water from the air, NaOH cannot be accurately weighed. To standardize 0.1 M NaOH, a solution is made to an approximate concentration of 0.1 M and then standardized by titrating an accurately weighed quantity of a primary standard.

Why is it necessary to standardize the NaOH solution?

It is necessary to standardize the NaOH solution to ensure accurate and consistent results in experiments or analyses. Standardization involves determining the exact concentration of the solution, which is important for precise measurements and reliable data.


How can one standardize NaOH?

To standardize NaOH, one must titrate it against a known concentration of an acid, such as HCl, using an indicator to determine the endpoint of the reaction. The volume and concentration of the NaOH can then be calculated based on the volume of acid used in the titration. This process ensures that the concentration of the NaOH solution is accurately determined for future use in experiments.


Why do we standardize the NaOH solution that we made by dissolving a measured mass of solid NaOH?

Standardizing the NaOH solution by dissolving a measured mass of solid NaOH ensures that the concentration of the solution is accurately known and consistent for use in experiments or analyses.


Why is it necessary to standardize a solution of NaOH using a primary standard, such as KHP?

It is necessary to standardize a solution of NaOH using a primary standard like KHP because primary standards are highly pure and have a known exact mass. This allows for accurate and precise determination of the concentration of the NaOH solution, ensuring reliable and consistent results in experiments.


How do you standardise 0.02 N NaOH?

To standardize 0.02 N NaOH, you would titrate it against a known concentration of an acid, such as a primary standard like potassium hydrogen phthalate. By carefully adding the NaOH to the acid until the endpoint is reached, you can determine the exact concentration of the NaOH solution.

Why is it necessary to standardize the NaOH solution before titration?

Standardizing the NaOH solution before titration is important to accurately determine its actual concentration. This ensures the accuracy and reliability of the titration results by eliminating any discrepancies that may arise from variations in the concentration of the NaOH solution.

This process helps researchers and scientists to make precise measurements and calculations in their work.


What is the common primary standard used in the laboratory to standardize of NaOH and HCl?

Sodium Carbonate (Na2CO3) is most commonly used to standardise acids as it is non-hygroscopic (doesn't absorb water from the atmosphere).Oxalic Acid (HOOCCOOH or H2C2O4) used to standardise bases

Suppose your laboratory instructor inadvertently gave you a sample of khp that was contaminated with nacl to standardize your naoh how would this affect the normality you calculated for your naoh sol?

Potassium acid phthalate is a common primary standard used to standardize bases. Obviously, it would depend upon how much NaCl was present, but the end result will be to reduce the amount of available H+ for the mass of KHP-NaCl mixture. That would cause you to understate the concentration of the base.

How do you standardize the sodium hydro oxide solution with oxalic acid?

Firstly, write out and balance your equation (as always!); this'll also require calculating the Molarity (mol of solute/ ml of solution). Next, you should already have an indicator (litmus strips or even red cabbage juice will work). Then add exactly the amount needed to neutralize the intended reagents. If you're doing the work on paper only, ignore this part: However, have you considered baking soda as opposed to NaOH? It's less dangerous.
