How can you prepare 0.02 N NaOH solution if i have .2N NaOH?
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.
What is the common primary standard used in the laboratory to standardize of NaOH and HCl?
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.
What is the calculation for 0.1 N naoh 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.
How do you get a 2.5 N NaOH solution in methanol?
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.
How do you prepare 10 N of 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.

0.5 N sodium hydroxide how to prepare?
To prepare a 0.5 N solution of sodium hydroxide (NaOH), dissolve 2 grams of NaOH in enough water to make 1 liter of solution. This will give you a 0.5 N (normal) solution of sodium hydroxide. Remember to handle NaOH with care and wear appropriate personal protective equipment.
How do you get a 2.5 N NaOH solution in methanol?
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.
How many ml of 6.0 N NaOH is required to neutralize 30 ml of 4 N HCL?
To find the volume of NaOH needed to neutralize HCl, we can use the equation: Moles of acid = Moles of base. Moles of HCl = Molarity of HCl * Volume of HCl, and Moles of NaOH = Molarity of NaOH * Volume of NaOH. Since HCl and NaOH react in a 1:1 ratio, we can set up the equation: (4N * 30ml) = (6N * Volume of NaOH) to solve for the volume of NaOH needed.
How do you prepare 10 N of 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.
What is a sentence with the word standardise?
The company decided to standardise their procedures across all departments to ensure consistency and efficiency.
How many moles NaOH would be in 450 mL of 0.25 N NaOH?
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.
How do you prepare 0.01 N NaOH from 0.02 N 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.
Can you give me a simple sentence using the word standardise?
standardise means making everythig the same.
How does make N NaoH?
It cannot N is Nitrogen where as Na is Sodium, they are two totally different elements
