Chemical reaction of metals with hydrochloric acid(HCl) produces salt & hydrogen gas

1. Reaction of Metals
with Acid

2. What is happening here?
Metals react with
acid
Bubbles of gas are
Produced

3. Testing the gas

4. Reaction of metal with Acid
Metal + Hydrochloric → Salt + Hydrogen
Acid

5. Do all metals react with acid in same
way?

6. Reaction of Magnesium with
Hydrochloric acid
Mg(s) + 2HCl(aq) → MgCl 2(aq) + H 2(g)
Reaction
Produces bubbles of hydrogen gas
Magnesium
Chloride
Magnesium hydrochloric
acid
Hydrogen
gas

7. Reaction of Aluminum with
Hydrochloric acid
2Al(s) + 6HCl(aq) → 2AlCl3(aq) + 3H2(g)

8. Reaction of Zinc with Hydrochloric
acid
Zn(s) + 2HCl(aq) →ZnCl2(aq) + H2(g)
Zinc reacts quickly with the acid to form
bubbles of hydrogen

9. Reaction of Iron with Hydrochloric
acid
Fe(s) + 2HCl(aq) → FeCl2(aq) + H2(g)

10. Reaction of Copper with Hydrochloric
acid
Copper
Does not react with dilute HCl
No bubbles
Temperature unchanged

11. Reaction of metal with nitric acid.
Hydrogen gas is not evolved when
a metal reacts with nitric acid.

12. Reaction of Aluminium with nitric
acid.
Nitric acid don't reacts with
aluminium
Because of formation of layer of
aluminium oxide
