Question

Which of the following product is formed when SiF4 reacts with water ?

Options

A.SiF3
B.H4SiO4
C.H2SO4
D.H2SiF4

Solution

reaction with water, SiF4(like SiCl4) gets hydrolysed to form H4SiO4 (Sillicic acid).
SiF4 + 4H2O → Si(OH)4 or H4SiO4 + 4HF
                                   (Silicic acid)
