Question

What is produced when lead reacts with dilute nitric acid?

Answer 1

Answer:

$Pb(NO_3)_2 + NO + H_2O$ is formed.

Explanation:

When lead( Pb) reacts with dilute $HNO_3$(nitric acid ) and

$Pb(NO_3)_2 + NO + H_2O$ is formed.

→ In this process a redox reaction takes place to produce the products.

Redox reaction:-

→ Redox is a chemical reaction in which the oxidation states of atoms in reactants to that of products are changed.

→ In this reaction two processes both a reduction process and a oxidation process takes place simultaneously.

Oxidation is Loss of electrons.

Reduction is gain of electrons.

Balanced chemical equation is:-

$3Pb + 8HNO_3 \rightarrow 3Pb(NO_3)_2 + 2NO + 4H_2O$

But,

When concentrated HNO3 is taken and reacted with lead the formation of PbO (lead oxide) takes place.
