Question

What is the formula of Titanium(II) oxide?

Answer 1

Hint: Titanium(II) oxide is an organic compound that contains titanium and oxygen. The formula can be derived by considering oxide ion as anion and titanium(II) as the cation. In a chemical formula, the cation is placed first followed by anion.

Complete answer:
• Titanium(II) oxide compounds have titanium with the oxidation state of plus two while the oxidation state of oxide ion is minus two.
• As Titanium(II) is a cation and has the formula $Ti$ so it will be written first in the molecular formula followed by the anion oxide with formula $O$.
• The proposed formula of the Titanium(II) oxide will be $TiO$. There will be no superscript or subscript as both have the same oxidation state and have net-zero charges.

Therefore, the formula of titanium(II) oxide is $TiO.$

Note:
• Titanium(II) oxide is a diatomic molecule that is not so stable and is found in an exoplanet atmosphere and interstellar medium or at a very high temperature.
• Acid solutions of $TiO$ are stable for a short time then decompose to give hydrogen.
• Titanium(II) oxide is prepared by the reaction of titanium dioxide and titanium metal at ${1500^0}C$.
