Question

Which of the following metal reacts with a base?

• A. $Pb$
• B. $Al$
• C. Both $A$ and$B$
• D. $Ag$

Answer 1

Answer: (C)

Both $A$ and$B$

An amphoteric compound is a molecule or ion that can react both as an acid as well as a base. The word is derived from the Greek word amphoteroi meaning both.

Examples of amphoteric metals such as copper, zinc, tin, lead, aluminium, and beryllium form amphoteric oxides or hydroxides.

So the correct option is C.
