How to make 2N of HCL from 100ml?
from 100 mL of what?
To make a 2N solution of HCl from 100 mL, you need to know the molar concentration of the HCl solution you are starting with.
The term "N" refers to normality, which is a unit of concentration equal to the number of equivalents of a solute per liter of solution. In the case of HCl, one mole of HCl dissociates into one equivalent of H+ ions.
Let's assume that you have a concentrated HCl solution with a molar concentration of x M. To determine the volume of the solution you need to make, you can use the equation:
NxV = N2xV2
Where:
N = Normality
V = Volume
Now, let's substitute the given values into the equation. We know that you want a 2N HCl solution, so N2 = 2:
xM x 100 mL = 2N x V2
Next, we need to convert the mL to liters by dividing by 1000:
xM x 0.1 L = 2N x V2
Now, rearranging the equation to solve for V2:
V2 = (xM x 0.1 L) / 2N
By substituting the known values, you can calculate the volume of the solution you need to make to obtain a 2N HCl solution from the given concentration.
Please note that it is important to handle concentrated HCl solutions with caution and follow appropriate safety measures such as wearing gloves, goggles, and working in a well-ventilated area.
