Question

name the acidic oxide. from the following --[Aluminium oxide, Sodium oxide, Phosphorus penta-oxide, Copper oxide, Sodium Hydroxide, Carbon monoxide]

Answer 1

$\LARGE{ \underline{ \bf{Required \: answer:}}}$

Only

• Phosphorus penta-oxide

Explanation:

Acidic oxides are generally the oxides of non-metals Out of the above group of oxides,

• Phosphorus pentoxide
• Carbon monoxide

are the oxides of non-metals. Rest are basic oxides or amphoteric oxides because they are the oxides of metals like Aluminium, Sodium, Copper etc. But carbon monoxide is nearly a neutral oxide.

• A neutral oxide is one that does not exhibit any tendency to form salts either with acids or bases.

So, we can say that we have only one acidic oxide. Do you know? Aluminium oxide is an amphoteric oxide because it can react with alkalis as well as acids.
