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.
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.
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 2 liters of 0.75 N Na OH?
Take 60 gm NaOH (100%) disolve it in distilled water, and make up to 2.0 liter by distlilled water.the prepared solution is 0.75 N NaoH 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 you prepare 0.2N of NaOH solution?
To prepare a 0.2N NaOH solution, dissolve 8 grams of NaOH in 1 liter of water. This will give you a solution with a concentration of 0.2N. Always remember to wear appropriate safety gear, such as gloves and goggles, when working with chemicals.
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.
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.
What is the ionic formula for sodium hydroxide?
NaOH and H2O form a solution of Na+(aq) and OH-(aq) ions (the solvent water, aq, is written as subscripted (aq) ) To make 1 Normal solution you need to know the equivalent of NaOH, which is calculated by dividing Molecular weight by 1, that is 40 divided by 1= 40. So the equivalent weight of NaOH is 40. To make 1 N solution, dissolve 40.00 g of sodium hydroxide in water to make volume of 1 liter.
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 make 300 ml NaOH 0.3N?
To make 300 ml of NaOH 0.3N solution, you would need to dissolve 2.7 grams of NaOH (sodium hydroxide) in enough water to make a total volume of 300 ml. Use a balance to measure the exact amount of NaOH needed, and make sure to dissolve it completely in the water to achieve a 0.3N concentration. Be cautious as NaOH is caustic and should be handled with care.
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.
