What happens when dilute hydrochloric acid is added to iron fillings? Tick the correct answer.

(a) Hydrogen gas and iron chloride are produced.

(b) Chlorine gas and iron hydroxide are produced.

(c) No reaction takes place.

(d) Iron salt and water are produced

 

Answer

(a) Hydrogen gas and iron chloride are produced.

 

Explanation

The chemical reaction between HCl and Fe (Iron fillings) can be written as follows

 

2HCl + Fe → FeCl 2 + H 2

 

Fe displaces H from HCl to form FeCl

(Fe being more reactive than H, displaces it from it’s from its compound)

K

Na

Ba

Ca

Mg

Al

Zn

Fe

Ni

Sn

Pb

H

Cu

Hg

Ag

Au

Pt

 

Thus,

Hydrogen gas and Iron Chloride are produced .
