# What happens when HCl is added to galvanised iron coil?

Mar 2, 2018

Zinc Chloride and Ferrous Chloride solution.

#### Explanation:

Assuming the reaction is all at room temperature:

What is galvanized iron coil?

Iron plated with zinc.

So initially the Hydrochloric acid wil react with zinc slowly like so:

$Z n + 2 H C l > Z n C {l}_{2} + {H}_{2}$

So you get Zinc Chloride and Hydrogen , the gas bubbles away.

Depending on the galvanishing thickness, you might have a situation where the iron gets exposed to the acid, which leads to this reaction:

$F e + 2 H C l > F e C {l}_{2} + {H}_{2}$
