22
Q

Why is silicon dioxide insoluble?

A

Silicon dioxide (SiO₂) has a giant covalent network structure, strong Si-O covalent bonds form a 3D network and the energy required to break these bonds is much higher than the energy released by hydration, making it insoluble in water.

23
Q

Why is Aluminium Oxide insoluble?

A

Aluminium oxide (Al₂O₃) has a high melting point and strong ionic bonding, the Al³⁺ and O²⁻ ions are held together by strong electrostatic forces and the lattice energy is greater than the hydration energy, preventing dissolution in water.
