If you have a standard solution of an acid, like hydrochloric or sulfuric, you can perform a titration in the presence of phenolphtalein or methyl orange and calculate the solution's normality or, you can weigh a sample of a strong solid acid ( orthoiperiodic acid or even oxalic acid), titrate the acid with the hydroxide solution, again in the presence of phenolphtalein or methyl orange and calculate the concentration of NaOH. If you want to have a solution with an exact concentration, let's say 1 molar, and the actual concentration is 1,33 molar, you simply calculate how much water you need to ad in a specific quantity of solution, to dilute it to exactly 1 molar.

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 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.
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
How many moles of NaOH were used in the titration process?
The number of moles of NaOH used in the titration process can be calculated by dividing the volume of NaOH solution used by the molarity of the NaOH solution.
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 do you standardization 1N hcl?
To standardize 1N HCl (hydrochloric acid), you would typically use a primary standard base, such as sodium hydroxide (NaOH), of known concentration to titrate the HCl solution. By carefully titrating the HCl with the NaOH, you can determine the exact concentration of the HCl solution. This information can then be used to adjust the concentration of the HCl solution as needed to make it accurately 1N.
What amount of NaOH is required to prepare 1N NaOH solution and why only that amount is used?
To prepare a 1N NaOH solution, you would need to dissolve 40 grams of NaOH in water to make 1 liter of solution. This amount is used because 1N solution means 1 mole of NaOH per liter of solution, and the molar mass of NaOH is 40 g/mol, so 40 grams of NaOH is needed to have 1 mole in 1 liter of solution.
Why did you use KHP to standardize the NaOH solution?
The reasons KHP is used as a primary standard are as follows: (1) It is not hydroscopic, (2) it has a high molecular weight, so a reasonable amount to titrate can be easily weighed, and (3) it is stable at temperatures over 100°C so that any water may be driven off by heating.
What is the molArity of a hydrochloric acid solution 30.0mL of which is just neutralized by 48.0mL of 0.100M NaOH?
The reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) is 1:1, so the moles of NaOH used in the reaction can be used to determine the moles of HCl in the solution. Using the volume and concentration of NaOH, you can calculate the moles of NaOH used. Then, using the balanced equation, you can determine the moles of HCl, which can be used to find the molarity of HCl in the solution.
How do you calculate of NaOH in solution procedure?
To calculate the concentration of NaOH in a solution, you would typically measure the volume of the solution and the amount of NaOH used to prepare it. Then, you can use the formula: Concentration (in mol/L) = amount of NaOH (in mol) / volume of solution (in L) to determine the concentration. Make sure to convert any given amount of NaOH from grams to moles before calculating.
Is NaOH aqueous?
Yes, NaOH (sodium hydroxide) is typically used in its aqueous form as a caustic alkaline solution.
How do you standardize 1N H2SO4 with a KHP?
To standardize 1N H2SO4 with KHP, you would first prepare a solution of KHP of known concentration. Then, titrate the KHP solution with the 1N H2SO4 solution until the endpoint is reached. The volume of H2SO4 used in the titration can then be used to calculate the exact concentration of the H2SO4 solution.
