Would the calculated molar mass be too high or too low if your standardized NaOH were exposed to the air for a long period of time after the standardization?
The calculated molar mass would be too high if the standardized NaOH were exposed to air for a long time. This is because NaOH absorbs carbon dioxide from the air, creating sodium carbonate (Na2CO3). This would make the solution more concentrated and lead to a higher-than-actual molar mass determination.
Conclusion of preparation of solution of HCl and NaOH to be standardized?
In the preparation of a solution of HCl and NaOH to be standardized, it is crucial to accurately measure the quantities of the reagents and ensure their purity. The solutions should be mixed thoroughly to ensure homogeneity, and the final solution can then be standardized using a primary standard such as potassium hydrogen phthalate (KHP) for acid or sodium carbonate for base. Conducting titrations afterward with the standardized solution will help determine the exact concentrations of the initial solutions.
Why do we standardize NaOH?
NaOH is standardized to ensure accurate and consistent results in experiments and analyses. Standardization involves determining the exact concentration of a solution, such as NaOH, by titrating it against a known standard solution. This process helps researchers and scientists to make precise measurements and calculations in their work.
How many grams of NaOH do you need to make 1 liter of a 10 percent sodium hudroxide solution?
To make a 10% NaOH solution, you would need 100 grams of NaOH per liter of water. So to make 1 liter, you would need 100 grams of NaOH.
5.012g of oxalic acid hydrate is dissolved in enough water to make 100 ml of solution. this solution is stitrated with a standardized NaOH solution. It required 39.40 ml of 2.02 M NaOH to reach the?

How to standardize 0.1N NaoH?
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.
How much of NaOH were used in the titration?
The amount of NaOH used in a titration depends on the volume and concentration of the NaOH solution used in the experiment. To calculate the exact amount of NaOH used, you would need to know the molarity of the NaOH solution and the volume used in the titration.
HOW many miles of NaOH are contained in 100.0 mL of 3.00 Miles NaOH?
There seems to be a misunderstanding, "miles" is not a unit of measurement for NaOH concentration. If you meant molarity instead of miles, you need the molarity of NaOH in order to calculate the moles of NaOH in the given volume which can be converted to miles using the molar mass of NaOH.
How would you know the Normality of HCL?
To determine the normality of HCl (hydrochloric acid), you can perform a titration experiment with a standardized solution of sodium hydroxide (NaOH) of known concentration. By recording the volume of NaOH required to neutralize the HCl, you can calculate the normality of the acid using the formula: Normality = (Molarity of NaOH) x (Volume of NaOH used) / Volume of HCl sample.
What volume of NaOH was used in the titration?
To determine the volume of NaOH used in the titration, you need to know the concentration of the NaOH solution and the volume required to reach the endpoint. Use the formula: volume NaOH (L) = volume HCl (L) * concentration HCl / concentration NaOH.
How to prepare 2N solution of NaOH in 10 ml of water?
To prepare a 2N solution of NaOH in 10 ml of water, you would need to calculate the amount of NaOH needed based on its molecular weight. Once you have determined the amount needed, dissolve it in 10 ml of water to make the solution. Remember to handle NaOH with caution as it is corrosive.
How to prepare 6N NaOH?
To prepare a 6N NaOH solution, you would need to dissolve 240 grams of sodium hydroxide (NaOH) pellets in enough distilled water to make 1 liter of solution. This will result in a 6N (Normal) solution of NaOH. Remember to handle NaOH with caution as it is a strong base and can cause burns.
