Oxidation Numbers of Tin and Oxygen

The video tutorial explains how to find the oxidation numbers for SnO2, also known as tin(IV) oxide. It begins by discussing the nature of neutral compounds and the requirement for their oxidation numbers to sum to zero. The tutorial then focuses on determining the oxidation number for oxygen, which is typically -2, and uses this information to calculate the oxidation number for tin in SnO2. The calculation is verified, ensuring that the sum of oxidation numbers equals zero, confirming the correctness of the process.

• Tin is always +4.

What is the typical oxidation number for oxygen in compounds?

• 0

• -1

• -2

• +2

Are there exceptions to the oxidation number rule for oxygen?

• No, but SnO2 is an exception.

• No, there are no exceptions.

• Yes, and SnO2 is one of them.

• Yes, but SnO2 is not one of them.

What must be the oxidation number of tin in SnO2 to balance the compound?

• 0
