Question

$\mathrm{BeO}$ Is Amphoteric Oxide Of Group (True Or False).

• A. True
• B. False

Answer 1

The correct option is A True

Beryllium oxide:

1. Group II element BeO is an amphoteric oxide, whereas other group II elements produce basic oxide.
2. It is a sign of Beryllium's aberrant behaviour and it exhibits a diagonal interaction with Aluminium.

The reaction of $\mathrm{BeO}$ with acid:

$\mathrm{BeO}\left(\mathrm{s}\right)+2\mathrm{HCl}\left(\mathrm{l}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{BeCl}}_2\left(\mathrm{s}\right)+2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)$

The reaction of $\mathrm{BeO}$ with base:

$\mathrm{BeO}\left(\mathrm{s}\right)+2\mathrm{NaOH}\left(\mathrm{s}\right)+{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)\to {\mathrm{Na}}_2\mathrm{Be}(\mathrm{OH}{)}_4\left(\mathrm{s}\right)$

Therefore, it is evident that it produces salt when interacting with both acid and base, indicating that it behaves as a base when reacting with acid and acid when reacting with base.
As a result, it is also an amphoteric oxide.

Hence, the given statement is true.
