MCQ

Which of the following product is formed when $SiF_4$ reacts with water ?

A
$SiF_3$
✓
$H_4SiO_4$
C
$H_2SO_4$
D
$H_2SiF_4$

✓

Answer

Correct option: B.

$H_4SiO_4$

b
In reaction with water, $SiF_4$ (like $SiCl_4$ ) gets hydrolysed to form $H_4SiO_4$ (silicic acid).

$Si{F_4} + 4{H_2}O \to \mathop {Si{{(OH)}_4}\,or\,{H_4}Si{O_4}}\limits_{{\text{(Silicic acid)}}} + 4HF$
