Beryllium hydroxide (Be(OH)\(_2\)) is amphoteric, meaning it can react with both acids and bases. This unique property distinguishes it from other group 2 hydroxides, which are typically basic.



Observe the following reactions (unbalanced):
\( P_2O_3 + H_2O \rightarrow X \)
\( P_4O_{10} + H_2O \rightarrow Y \)
The number of \( P=O \) bonds present in \( X, Y \) are respectively:
Observe the following reactions (not balanced):
Cl2 + NaOH → NaCl + X + H2O
Cl2 + NaOH → NaCl + Y + H2O
