What happens when HCl is added to galvanised iron coil?
Zinc Chloride and Ferrous Chloride solution.
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:
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:
