What is the formula of Tin (IV) oxide?

Options

ASn ₂ O ₃
BSnO ₂
CSnO ₄
DSnO

Correct answer

B. SnO ₂

Step-by-step solution

The oxidation state of Tin (Sn) in Tin (IV) oxide is +4 . The oxidation state of Oxygen (O) in an oxide ion is -2 . To form a neutral compound, the total positive charge must balance the total negative charge. Two oxide ions are required to balance one Tin (IV) ion. Using the criss-cross method, the formula is initially Sn ₂ O ₄ , which simplifies to the empirical formula SnO ₂ . Answer: SnO ₂
