SiF4 + H2O -> H4SiO4 + HF — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Silicon tetrafluoride (SiF4) undergoes hydrolysis because silicon has vacant 3d orbitals to coordinate with the lone pairs from water molecules. Step 2: The reaction yields orthosilicic acid (H4SiO4) and hydrofluoric acid (HF). The silicon atom stays in its +4 oxidation state in H4SiO4. Step 3: The silicon-containing product, silicic acid, ends with the '-ic' suffix, which classifies the process under category A.
