Question

What happen when dilute hydrocloric acid is added to iron fillings?

Answer 1

Answer:

Explanation:

When dilute hydrochloric is added to iron when it reacts with it to form the salt ferrous Chloride and release hydrogen gas..

Fe(s) + dil.2HCl(aq)——> FeCl2(aq) + H2(g).

Generally this reaction may not occur because Iron has some different type of the resistivity against its corrosion since the acid used is 'diluted'

If the acid used is concentrated in the reaction is sure to happen..
