Iron reacts with HCl solution to give H2 gas and Fe2+ ions. Suppose that 4.4 g of iron are to be dissolved in 1.8 M HCl. What is the minimum volume (in mL) of the acid solution required to react with all of the iron?


Expert Answer

Step 1

The required balanced chemical reaction is given below.

Fe(s) + 2HCI(aq) -> Fe* (аq) + 2C1(аq) + Н, (g)

Fe(s) + 2HCI(aq) -> Fe* (аq) + 2C1(аq) + Н, (g)

Step 2

From the above balanced chemical equation, it can be stated that 1 mole of Fe is reacting with 2 mol...

Actual moles of Fe
Molar mass 55.845g/mol
Actual moles of HCl 2 x 0.0788 mol = 0.1576 mol
