what is the name of this chemical formula SnO2?
The Correct Answer and Explanation is:
The chemical formula SnO₂ represents tin(IV) oxide, also known as stannic oxide.
Explanation:
- Tin (Sn) is a metal element from the group 14 of the periodic table, with atomic number 50. It has two common oxidation states: +2 and +4. The oxidation state is indicated by Roman numerals in parentheses. In SnO₂, the tin atom is in the +4 oxidation state, which is why it is called tin(IV) oxide.
- Oxygen (O) is a non-metal element and typically forms a -2 charge when bonded with metals. In SnO₂, there are two oxygen atoms, each contributing a -2 charge, leading to a total charge of -4 from the oxygens. To balance this, tin must have a +4 charge, which is consistent with its +4 oxidation state in this compound.
- The compound SnO₂ is a white, odorless powder, and is commonly found as a natural mineral called cassiterite, which is the primary ore of tin. It has important industrial applications, such as in the production of tin and in the manufacture of ceramics, glass, and electronics. It also serves as a catalyst in certain chemical reactions, such as in the catalytic oxidation of organic compounds.
Additional Uses:
- Tin(IV) oxide is used in the production of transparent conductive coatings for glass, which are employed in energy-efficient windows and displays.
- In some cases, it can also be used in solar cells and as a catalyst in organic reactions.
Thus, SnO₂ is an important compound in various industrial and technological processes, and understanding its structure and uses highlights its versatility.
