Question

Differentiate between iron and copper in terms of their reactivity towards dilute hydrochloric acid. Write the chemical equations involved

Answer 1

Since Copper is lower than Hydrogen in the reactivity series so it cannot liberate Hydrogen. Equation for this-

Cu(s) + HCl(aq)--------> no reaction

________________________________________

In the case of Iron, Iron is placed above hydrogen thus it can liberate hydrogen in reaction with Hydrochloric Acid. Equation for this-

2Fe(s) + 6HCl(aq) -------------> 2FeCl2(aq)+ 3H2(g)
