Write the name of Pb2O3
The correct answer and explanation is:
The compound Pb₂O₃ is named Lead(II) oxide.
Explanation:
Lead(II) oxide is a compound formed between lead and oxygen, where lead has an oxidation state of +2. The “II” in the name indicates that lead is in its +2 oxidation state, as opposed to the +4 state seen in other lead oxides, such as PbO₂ (Lead(IV) oxide).
The chemical formula Pb₂O₃ can be derived from the empirical ratio of lead to oxygen atoms. In this compound, there are two lead atoms for every three oxygen atoms. The oxidation state of lead in this compound can be determined by considering the fact that the total charge must balance out to zero. Oxygen typically has an oxidation state of -2, so with three oxygen atoms, the total negative charge is -6. To balance this, the two lead atoms must have a combined positive charge of +6, meaning each lead atom is in the +2 oxidation state.
Lead(II) oxide is commonly found in various industrial applications, such as in batteries and in the manufacture of lead glass. It is also used as a precursor in the production of other lead compounds. Additionally, it can form in different polymorphic forms, such as the more commonly known litharge (α-Pb₂O₃) and massicot (β-Pb₂O₃), which have distinct physical properties and uses.
It’s important to note that lead compounds, including Pb₂O₃, can be toxic, and appropriate care should be taken when handling them, particularly in industries where lead exposure might occur.
