How to prepare 0.01 N Hcl Solution in pharma?

How to prepare 0.01 N Hcl Solution:

Here is the calculation for the required quantity of HCl for the preparation of 0.01N hydrochloric acid.

Weight of HCl (In gm) = Normality x Equivalent weight x Required quantity

Here, Normality = 0.01 N

Equivalent weight of HCl = 36.5 g/mol

Required Qty = 1000 ml = 1 L

Therefore,

Weight of HCl (in gm) = 0.01 x 36.5 x 1 = 0.365 gm

Preparation of 0.01 N Hcl Solution:

1. Carefully weigh the 0.365 gm of HCl.
2. Transfer the weighed quantity of Hcl into 1000 ml of volumetric flask.
3. Dilute to volume with water.

The pH for the solution should be around 2.0

By using the same formula you can calculate the required quantity of HCl for any dilutions.
