How much hydrochloric acid is required to produce 11.2 liters of chlorine?

One mole of ideal gas under normal conditions takes a volume of 22.4 liters.

Let’s determine the amount of substance that is in 11.2 liters of chlorine ..

n Cl2 = 11.2 / 22.4 = 0.5 mol;

Chlorine has the chemical formula Cl2. Its molecule consists of two chlorine atoms.

Hydrogen chloride has the chemical formula HCl. Its molecule contains one chlorine atom.

Therefore, chlorine production requires twice the amount of hydrochloric acid.

To get 0.5 mol of chlorine, you need to take 1 mol of hydrogen chloride.
