Red Lead Pb3O4 :- What is the ratio of Pb +2 and +4 oxidation states in this.
If you find any links then please give it.

If it were solely lead (II), what would the formula of the oxide be? What about if it were solely lead (IV)?

I meant that I have read that Pb3O4 is a mixture of PbO and PbO2 So what is the ratio of these in the mixture.

Pb3O4 Can carry out the reactions of PbO and PbO2 so i need to find the ratio of +2 and +4 in this.

OK, so you can set up two equations x + y = 3 (for atoms of lead) and x + 2y = 4 (for atoms of oxygen), where x is the amount of lead (IV) oxide and y the amount of lead (II) oxide...

Of course, in this case it's relatively easy by trial and error....

Thank you. I got it.
