How do you prepare 2M HCl solution from HCl?

Answer 1

Step 1

The easiest way to make a 5 Molar HCl solution is following

Consider that your stock HCl concentration is 37.5% and S.G 1.189 gms / ml and formula weight for HCl is 36.46 gms / mole

Step 2

Now determine the Molarity of the stock Solution

Percentage x S.G / Molecular Weight

37.5 x 1.189 x 1000 / 100 * 36.46

Molarity of Concentrated - Stock HCl = 12.23 moles / liter or M

Now, to make a 5 molar solution

MiVi = MfVf

Vi = Mf x Vf / Mi

Vi = 5 x 1 / 12.23

Vi = 0.409 liter or 408.9 ml

Answer 2

To prepare a 5M HCl solution, you need to know the concentration of your source of HCl. Then you can use this proportion C1V1=C2V2, where C=Concentration in M(moles/liter) and V=Volume(liters).

Answer 3

There is 2 formula you need to know:

M: n/V and n: m/Ma Ma: Molecular mass of HCI

First step calculate the mol 2M: n/ 0.1 n: 0.2

n: m/Ma 0.2: m/ 36.5 m:7.3

Preparation: Get 7.3 ml of HCI pour it in the graduated cylinder (100ml) and add distilled water until it reaches 100ml.

Thats all.

Answer 4

M is for moles/L. So, you all you would need to do is add 2 times the amount in L of water to the solid HCl. For example, if you have 3 moles of solid HCl, add 6 L and you will have .5M HCl.

Answer 5

Add 1M HCl solution to an equal quantity of water

Answer 6

Take 10 mls. of 1M HCl and add distilled water till total volume becomes 100mls. now it is 0.1M HCl.

Answer 7

Simply add the distilled water to 1N solution and make the volume doubled.
