Question

Out of the following elements, choose the elements which are capable of forming amphoteric oxides.

• A. Zinc and Aluminium
• B. Iron and Aluminium
• C. Nickel and Zinc
• D. None of these

Answer 1

The correct option is A

Zinc and Aluminium

An amphoteric compound is a molecule or ion that can react both as an acid as well as a base. Many metals (such as copper, zinc, tin, lead, aluminum, and beryllium) form amphoteric oxides or hydroxides. Amphoterism depends on the oxidation states of the oxide.

So, here from the options, we can say that Aluminum and zinc are capable of forming amphoteric oxides.
