Question

Beryllium oxide is treated separately with aqueous HCl and aqueous NaOH solutions.

✓

Answer

Beryllium oxide (BeO) is an amphoteric oxide and thus, it reacts with both acid $( HCl )$ as well as base $( NaOH )$ to give the corresponding products.
i. $BeO +\underset{(\text { Acid })}{2 HCl } \longrightarrow BeCl _2+ H _2 O$
ii. $BeO +\underset{(\text { Base })}{2 NAOH } \longrightarrow Na _2 BeO _2+ H _2 O$
