How much of 35 percent HCl would be needed to make 1 percent HCl?
To make a 1% HCl solution from a 35% HCl solution, you would need to dilute the concentrated solution with water. The ratio of concentrated HCl to water would be approximately 1:34. So, to make 1% HCl, you would mix 1 part of the 35% HCl solution with 34 parts of water.
Where do you get the 82.81 ml during the preparation of 1 N solution of HCl from a concentrated 37 percent HCl?
Try a gradual measuring pipet max. 100 mL from which you'll get 83 (+/- 1) mL. More accurate then this is not easily done and besides that it's also not usefull: the given concentrated 37% is also accurate between 36% - 38%, so you'll never get an exact 1.00 N HCl.
How do you prepare 0.1 N solution HCL from 1N?
Add 100 mL of HCl 1 N in a 1 L volumetric flask, class A or B; add ca. 850 mL distilled water to the flask. Place the flask in a thermostat at 20 0C. After 30 min add slowly distilled water to the mark (1 L) and stir well the closed flask. Pour the solution in a bottle. Place a label with the date, concentration, name of the solution on the bottle.
How will you prepare one liter of 0.1 N HCL solution from 12 N HCL?
To prepare 1 liter of 0.1N HCl solution from 12N HCl, you would need to dilute the 12N HCl by a factor of 120. To do this, you would add approximately 83.33 mL of 12N HCl to a container and then dilute it with water to reach a final volume of 1 liter. Make sure to mix the solution thoroughly after dilution.
What is lab normality of hcl?
The normality of a solution is a measure of the concentration of a solute in a solution. For HCl (hydrochloric acid), the normality would depend on the concentration of the HCl solution. For example, a 1 M (molar) solution of HCl would be 1 N (normal).

How many Normal is equal to 12 HCl?
To find out how many normal (N) solutions are equivalent to 12 hydrochloric acid (HCl), we need to consider the reaction in which HCl donates protons. HCl is a strong acid and fully dissociates in solution, providing one proton (H⁺) per molecule. Therefore, a 1 N solution of HCl is equivalent to 1 M (molar) solution. Thus, 12 HCl would correspond to 12 N if we are considering the same volume of solution.

The normality of a solution is a measure of the concentration of a solute in a solution. For HCl (hydrochloric acid), the normality would depend on the concentration of the HCl solution. For example, a 1 M (molar) solution of HCl would be 1 N (normal).
25 percent is equal to 850 what is 1 percent?
Designate the unknown base number as n. Then 0.25 n = 850 or n = 3400. 1 percent of this is 34.
How many ml of 6.0 N NaOH is required to neutralize 30 ml of 4 N HCL?
formula for neutralizatrion is volume of acid X normality of acid = volume of base X normality of base so (0.3)(3) should equal (4)(volume) which is .225L. However, Ca(OH)2 contains 2 moles of OH resulting division of total volume needed by 2. Thus, the answer becomes .1125L or 112.5ml.
How do you convert 0.1 N HCl to 0.01 N HCl?
To convert 0.1 N HCl to 0.01 N HCl, you can perform a dilution. For example, mix 10 mL of the 0.1 N HCl solution with 90 mL of distilled water to achieve a total volume of 100 mL, resulting in a 0.01 N HCl solution. The dilution factor here is 10, as you are reducing the concentration by a factor of ten.
Is a 38 percent HCl sol same as 12 N HCl?
No, a 38% HCl solution is not the same as a 12N HCl solution. The concentration of a solution is based on the amount of solute dissolved in a specific volume of solvent. A 38% HCl solution means there is 38 grams of HCl in 100 mL of solution, while a 12N HCl solution means there are 12 moles of HCl in one liter of solution.
What is the percent yield of NH3 plus HCl -- NH4Cl?
The percent yield is the actual yield divided by the theoretical yield, multiplied by 100%. In the reaction of NH3 and HCl to form NH4Cl, the theoretical yield is determined by the limiting reactant. If the actual yield of NH4Cl obtained from the reaction is 80%, for example, the percent yield would be 80%.
How do you convert 37 percent HCL in normality?
Density of HCl = 1.186 g/mL Molar Mass HCl = 36.46g/mol We want a concentration in mol/L so we will first convert density into g/L (1.186 g/mL)(1000mL/1L) = 1186 g/L We must now know what density 37% of that is (0.37)(1186 g/L) = 438.82 g/L Now divide this density by the molar mass to cance out the g and give you mol/L (concentration) C = (438.82g/L)/(36.46g/mol) C = 12.04 M Since HCl is monoprotic, 1M = 1N. Therefore, 37% HCl is ~12N
