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.
To prepare a 0.02 N NaOH solution from a 0.2 N NaOH solution, you can dilute the 0.2 N solution by adding 10 times the amount of water. For every 1 part of the 0.2 N solution, add 9 parts of water. Ensure thorough mixing to obtain a 0.02 N NaOH solution.
The common primary standard used to standardize NaOH and HCl solutions is potassium hydrogen phthalate (KHP). KHP is a solid acid that can be accurately weighed and dissolved in water for titration with the NaOH or HCl solution.
To calculate the concentration of a 0.1 N NaOH solution, you need to know the molar mass of NaOH which is approximately 40 g/mol. Since 1 N solution is equivalent to 1 gram equivalent weight of the solute dissolved in 1 liter of the solution, a 0.1 N NaOH solution would contain 4 g of NaOH per liter of solution.
To prepare a 2.5 N NaOH solution in methanol, you would first calculate the amount of NaOH needed based on its molar mass and the desired concentration. Then, dissolve this amount of NaOH in the appropriate volume of methanol to make the 2.5 N solution. Be sure to wear appropriate safety gear and follow proper handling procedures when working with NaOH.
To prepare a 10 N solution of NaOH, you would dissolve 400 g of NaOH pellets in enough distilled water to make 1 liter of solution. Remember to add the NaOH to the water slowly and carefully due to the exothermic nature of the reaction. Finally, stir the solution until all of the NaOH has fully dissolved.

The company decided to standardise their procedures across all departments to ensure consistency and efficiency.
First, calculate the number of moles of NaOH: Moles = Molarity x Volume (L) Convert mL to L: 450 mL = 0.45 L Moles = 0.25 N x 0.45 L = 0.1125 moles of NaOH.
To prepare 0.01 N NaOH from 0.02 N NaOH, you can dilute the 0.02 N solution by adding an equal amount of water. This will effectively halve the concentration of the solution, resulting in a 0.01 N NaOH solution. Remember to mix the solution thoroughly after dilution.
standardise means making everythig the same.
The pH of a 1 millimolar NaOH solution is approximately 11. The concentration of a 1 millimolar solution is 0.001 mol/L, and NaOH is a strong base that completely dissociates in water to produce hydroxide ions, leading to a basic pH.
To prepare 0.25N sodium hydroxide solution, you would need to dissolve 2.0 grams of sodium hydroxide (NaOH) in enough water to make 1 liter of solution. This will give you a solution with a concentration of 0.25N. Remember to wear appropriate safety gear when handling NaOH, as it is corrosive.
It cannot N is Nitrogen where as Na is Sodium, they are two totally different elements
