Question

1. What is the systematic name for P₂O₅?

2. What is the ionic charge for the lead ion in Pb(C₂H₃O₂)₂?

Answer 1

1) Systematic name of P₂O_{​​​​5} is Phosphorous (V) Oxide. Here the Roman numeral specified in brackets ie V corresponds to the oxidation state of phosphorus.

It is also called Diphosphorous pentoxide or Phosphorus Pentoxide

2)

Here anion is acetate ion.

It's formula is CH_{​​​​​3}​​COO^​-

As its oxidation state is -1 and there are two acetate ions are present, ionic charge present on Pb is +2.

Let charge on Pb is x

Since charge on acetate is -1 and 2 acetate ions are present,

x+2(-1) = 0

x = +2

Compound name is Lead (II) Acetate
