Question : 65 of 150

Marks: +1, -0

What is the formula of Tin (IV) oxide?

Solution:

Concept:

The Roman numeral (IV) indicates the oxidation state of tin, which is

+4

Explanation:

Tin (IV) forms the ion

\mathrm{Sn}^{4+}

Oxygen forms the oxide ion

\mathrm{O}^{2-}

To balance the total charge, one

\mathrm{Sn}^{4+}

ion combines with two

\mathrm{O}^{2-}

ions.

Thus, the ionic formula becomes

\mathrm{SnO}_{2}

Answer:

\mathrm{SnO}_{2}

(Option B).
