Solution

The correct option is A
Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.

Statement 1: Non-metallic oxides are usually acid anhydride.

Statement 2: Nonmetallic oxides form acids when placed in water.

Both Statement 1 and Statement 2 are correct and Statement 2 is the correct explanation of Statement 1.

For example, phosphorous pentoxide $P_{2} O_{5}$ is a non-metallic oxide.

It is anhydride of phosphoric acid. On dissolution in water, it forms phosphoric acid.

$P_{2} O_{5} + 3 H_{2} O \to 2 H_{3} P O_{4}$

Hence, the correct option is A.
