← ScienceWhich reaction occurs when hydrofluoric acid dissolves glass?
A)Covalent bond disruption of silicon dioxide✓
B)Hydrogen bond destruction between silanols
C)Electrostatic attraction increases for dissolved ions
D)Metallic bonding weakens silicate network energies
💡 Explanation
Glass etching occurs because hydrofluoric acid induces nucleophilic attack affecting the covalent bonds in SiO₂, resulting in the formation of hexafluorosilicates via chemical transformations. Therefore, the covalent bonds are disrupted rather than hydrogen bonds since HF directly reacts with the silica itself.
