Question

Which of the following options contain amphoteric oxide(s) only?

• A. $SnO_2 \;and \;SiO$
• B. $SiO_2$
• C. $SnO_2 \;and \;PbO_2$
• D. $CO \;and\; SiO$

Answer 1

Answer: (C)

$SnO_2 \;and \;PbO_2$

Answer 2

Amphoteric oxides are those that can act as both acidic and basic oxides depending on the reaction conditions. They can react with both acids and bases to form different products.
Among the given options, the oxides that are commonly recognized as amphoteric are $SnO_2$​ and $PbO_2​$. Both tin dioxide $(SnO_2​)$ and lead dioxide $(PbO_2​)$ exhibit amphoteric properties.

The Correct Option is (C) : $SnO_2 \;and \;PbO_2$
