Question

What is the formulaLead (II) Oxide ​

Answer 1

Answer:

The formula for Lead(ll) Oxide is PbO.

Explanation:

The symbol for Lead is Pb.

The symbol for Oxygen is O.

Given,Oxidation state of Pb = +2

We know,

Oxidation state of Oxygen in all Oxides is the same and is equal to -2,

Let the no. of Pb atoms in the oxide = x;

no.of Oxygen atoms = y;

Concept:

Sum of oxidation states of all atoms in any compound is equal to zero.

Applying concept,we get,

x(+2) + y(-2) = 0

x(+2) = y(+2)

Therefore, x = y

and, x : y = 1:1 ;

Therefore the empirical and the correct formula of the oxide is $Pb_{1}O_{1}$,which is $PbO$.
