1n naoh solution preparation from 10n naoh?
The dilution ratio is 1/10 (1 part 0,1 N solution mixed with 9 parts water).
How do you prepare a 10N naoh solution with pellets?
Make sure to use goggles and gloves, because sodium hydroxide is very caustic, and the mixture can get very hot (reaction is very exothermic). 1) Weigh out 400 grams (10 moles) of NaOH pellets. 2) Place 1 liter of water in a large borosilicate beaker (at least 2 liter volume) or other container that can handle very caustic substances. 3) Begin slowly adding NaOH pellets to your beaker or container and stirring. If using a glass container, you may want to have it set in an ice bath from the beginning to keep the temperature down, since the solution will begin to get hot as the sodium hydroxide dissolves. Continue until all of the pellets have dissolved in the 1 liter of water. This will produce a 10 molar solution of NaOH. Since 1 mole of NaOH dissociates in water to form 1 mole of Na+ ions and 1 mole of OH- ions, this will also produce a 10 N (in terms of normality) solution of NaOH.
How can you make 10N NaOH?
You need 400 g of solid NaOH dissolved in water and made up to exacly 1 liter in a volumetric flask. For 1 L solution: 1. Weight 399,9711 g of NaOH per analysis with an analytical balance. 2. Put the NaOH in a clean and dry Berzelius beaker. 3. Add very slowly and by stirring 500 mL water distilled (deionized); avoid the superheating. 4. Transfer quantitatively this solution in a 1 L volumetric flask. 5. Put the flask in a thermostat at 20 0C. 6. Wait for the temperature stabilization of the flask with the solution. 7. Add slowly distilled (deionized) water to the mark. 8. Stir the volumetric flask. 9. Put on the flask a label with: name of the reagent, concentration, date, operator.
How do you prepare the 10N HCl solution?
weigh out 365g of HCl pellets and dilute to 1 liter to prepare the 10N HCl solution. Reasons:N is short for NORMAL SOLUTIONS, The definition of a NORMAL SOLUTION is a solution that contains 1 gram equivalent weight (gEW) per liter solution. An equivalent weight is equal to the molecular weight divided by the valence (replaceable H ions). eg：1N NaCl = 58.5 g/L 1N HCl = 36.5 g/L 1N H2S04 = 49 g/L Problems involving normality are worked the same as those involving molarity but the valence must be considered: 1N HCL the MW= 36.5 the EW = 36.5 and 1N would be 36.5g/L 1N H2SO4 the MW = 98 the EW = 49 and 1N would be 49 g/L 1N H3PO4 the MW = 98 the EW = 32.7 and 1N would be 32.7 g/L so,u can weigh out 365g of HCl pellets and dilute to 1 liter to prepare the 10N HCl solution.
What is N10 HCL and how will you prepare it?
N10 HCl would be 10 M HCl. You might mean N/10 which would be 0.1 M. (N or normal is an old-fashioned way to define chemical concentrations. Most chemists prefer M or molar concentrations.) Just take some higher-concentration HCl and dilute it to get the desired concentration. Use the dilution formula C1V1 = C2V2 to figure out how much high-concentration HCl to use for the volume of dilute HCl you want to make. If anything here doesn't make perfect sense, you probably shouldn't be working unsupervised with chemicals, and if you don't know what HCl is then you definitely shouldn't do whatever it is you are trying to do. 10 M HCl is a caustic liquid that gives off caustic vapors so wear goggles and be careful with it.

What is the most efficient way to make up a HEPES buffer at pH 8.5 What starting compounds and reagents will you use?
You will need to purchase the HEPES powder and then you have to mix with desired amount of sterilized destilled water and check for the pH, if too low you can add KOH or NaOH, and if its too high u can add HCl until desirable pH you want. Then Filter sterile the solution, cover the bottle with Aluminium foil and store at 4 degree. For 500 ml 1M HEPES buffer, I had to add at least 10 ml 10N NaOH or KOH to bring the pH up towards pH 8.5
5 x 10n equals 0.005 what is the formula for this equation?
If you're asking for a SOLUTION, 5 x 10n=0.005 => 50n=0.005 Divide 50 for the both side =>n=0.005/50.
