The reaction of granulated zinc with dil HCl results in the formation of dihydrogen.
The reaction between zinc metal and dil HCl
The reaction between zinc metal and HCl
Zn + HCl → H2 + ZnCl2
Zinc granules are the solid crystals of zinc, it reacts easily with the acid to produce hydrogen bubbles.
- It is a single replacement reaction in which hydrogen is displaced by zinc metal to form hydrogen gas and a salt, zinc chloride.
- Zinc chloride is formed when Zn is combined with dilute sulphuric acid and hydrogen gas is liberated.
- The reaction is exothermic, and thus the reaction generates heat.
