How do you prepare 1n hcl solution?

Answer 1

You must take 88,8 mL concentrated HCL and fill up to 1000 mL with distilated water. (REMEMBER: ALWAYS ADD ACID TO WATER! - add 88.8mL to 900mL water and dilute to final volume = 1L)

The simplest and still pretty accurate answer would be based on the following things. The concentrated HCl means it is 12M. You can simpy use M1*V1=M2*V2 formula to calculate what You are looking for. In this case You do not have to worry switching from normal solution to molarity since 1M is = to 1 N for HCl.

Using M1*V1=M2*V2, where M stands for molarity and V for volume:

12M *X(unknown volume) ml (in mililiters) = 1 N (or 1M) * 1000 ml

1000 ml*M /12 M = 83.33(3) ml

Answer 2

The density of 36% HCl is not 1000 g/L. it is closer to 1.48 g/ml. 1000 g/L is the density of water.

using 1.48 g/ml means 100 ml would contain 148 g solution = .36x148 g HCl = 53.3 g HCl = 53.3 g / (36.5 g/mole) = 1.46 moles. if you dilute that to 1L you get 1.46 N HCl not 1N...

***************************

this is the correct way to do this problem....

***************************

let's use a 1000 ml volumetric flask. This will make 1000 ml of a 1N solution of HCl and will require this many grams of HCl

fyi. 1 N means 1 mole of equivalents per L solution and an equivalent is what we "chemists" and "chemical engineers" call an H+ ion or an OH- ion. HCl has 1 equivalent per molecule of HCl. H2SO4 has 2....

1000 ml solution x (1 mole equivalents / 1000 ml) x (1 mole HCl / 1 mole equivalents ) x (36.5 g HCl / mole HCl ) = 36.5 grams HCl. that's what you need in the flask to make your 1 N solution.

so how much of the 36% solution do you need? 36% by the way is based on mass. 36 g HCl / 100 g of solution....

so 36.5 g HCl x (100 g solution / 36 g HCl) = 101.39 grams solution.

the answer is about 100 grams. not 100 ml.... at 1.48 g/ml, 100 g = 100g x (1 ml / 1.48g) = 67.6 ml.....

*************** so make this solution this way ***********

read the temp requirement on the volumetric flask. fill the flask 1/2 full of distilled water. SLOWLY add 101.39 grams of your 36% HCl solution to the flask (put the flask on a balance, zero the balance, add the acid to 101.39g with a pipette if you want) . swirl the flask for a minute or so. add more water to about 90% of the way to the volumetric mark. cool the flask to the temperature indicated on it (like 25C) then fill the rest of the way to the mark with distilled water. then stopper it with a glass stopper and invert it several times to mix....
Use the equation: MaVa=MbVb

M= molarity V= volume

Answer 3

You must determine the concentration first of the concentrated HCl, typically concentrated HCl is a 36-38% HCL which works out to about 12-12.2 N concentration. From there all you have to due is dilute down to 0.1N.

Answer 4

You can prepare 0.01M HCl from 1M HCl by diluting it with water. To find the amount of water to dilute it with, we use the formula: M1V1=M2V2. If you need 100mL of the 0.01M acid, then we plug in the concentrations and volume:

(1M HCl)V1= (0.01M HCl)(100mL), and it solves to V1=1mL.

So, 1mL of 1M HCl diluted with 99mL water will make 100mL of 0.01M HCl.

Answer 5

Take specific volume of 3N solution and increase the volume three times by adding distilled water.
