Question

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

Answer 1

By using `M_(dilution)timesV_(dilution) = M_(first)timesV_(first)`

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:

`0.002times5000 = 0.36timesV`

V is volume of HCl from stock (original).

You will find

`10 = 0.36timesV`

`V= 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).
