Subjects Chemistry
Reaction of Zinc metal with sulphuric acid.
Q-1 Write the reaction involved in this Activity.
Q-2 Why does Zinc displaced hydrogen from sulphuric acid? Q-3 Which gas is evolved when Zinc metal react sulphuric acid? ​

Answer 1

Answer:

1. Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. 

$zn + h2so4 = znso4 + h2$

2. Zinc is more reactive than hydrogen and it displaces hydrogen from dilute acids. Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. This is a single displacement reaction of a non-metal by a metal.

3. Hydrogen

Answer 2

Answer:

1. Zn + H2So4 = ZnSo4 + H2

2. Hydrogen is displaced by zinc because displacement reaction occurs and zinc idore reactive than hydrogen

3. Hydrogen
