Question

Zinc granules react with hydrochloric acid to form zinc chloride amd hydrogen gas

Answer 1

Answer:

We know that,

Metal + Acid = Salt + Hydrogen gas

Same case followes here.

Since most of the metals are more reactive that hydrogen gas, they displace hydrogen from its solution.

The presence of hydrogen can be tested by bringing a lighter near the beaker and the fire burns with a pop sound.

Reaction:

Zn(s) + 2HCl(aq) = ZnCl2 (s) +

H2(gas)

Here ,

Zn = zinc metal (metal)

HCl = Hydrochloric acid (acid)

ZnCl2 = Zinc Chloride (salt)

H2 = Hydrogen gas
