Nascent hydrogen refers to hydrogen that is liberated during a chemical reaction.

Nascent hydrogen is obtained from the reaction between

Sodium reacts with ethanol to form sodium ethoxide and ethanol. Write the balanced chemical equation.

Na + C2H5OH → C2H5ONa + [H]

Aluminium reacts with sodium hydroxide to liberate nascent hydrogen.
Write the balanced chemical equation.

Al + 2 NaOH → Na2AlO2 + 2 [H]

Zinc reacts with dilute sulphuric acid to form zinc sulphate and nascent hydrogen.
Write the balanced chemical equation.

Zn + dil H2SO4 → ZnSO4 + 2 [H]

Why is nascent hydrogen so active?

Nascent hydrogen is most powerful reducing agent than ordinary hydrogen because nascent hydrogen is in atomic state and atoms are more active than molecules, nascent hydrogen is evolved in small bubbles containing the gas under great pressure, nascent hydrogen is activated by the energy liberated in the reaction in .

Atomic Hydrogen vs Nascent Hydrogen
Atomic hydrogen refers to hydrogen obtained by dissociation of molecular hydrogen.	Nascent hydrogen refers to hydrogen that is liberated during a chemical reaction.
Application
Atomic hydrogen is an isolated form of hydrogen, which is highly reactive and energetic; it is a major component in the universe.	Nascent hydrogen is the initial atomic state of hydrogen that is formed during a chemical reaction.
