How to prepare 0.2% of Hcl 36% in a water tank its volum is 5000 litre?

By using ${M}_{\mathrm{di} l u t i o n} \times {V}_{\mathrm{di} l u t i o n} = {M}_{f i r s t} \times {V}_{f i r s t}$

Explanation:

You have 36% HCl (that is your stock). Your final volume will be 5000 Liters and your final concentration will be 0.2%.

Use the formula provided above:

$0.002 \times 5000 = 0.36 \times V$

V is volume of HCl from stock (original).

You will find

$10 = 0.36 \times V$

$V = \frac{10}{0.36} = 27.78$ Liters.

It means take 27.78 Liters of 36% HCl and add to the water tank (final volume is 5000 Liters).
