Question

The valency of sulphur in SO3 is: A two, B Three, C Four, D six​

Answer 1

Answer:

The valency of sulphur is six.

Explanation :

$S^{6+}$                $O^{2-}$

dividing both the terms by 2 to obtain a simple ratio

⇒ $S^{3+}$                  $O^{1-}$

on interchanging the valency number;

$S^{1}$                    $O^{3}$

therefore the compound obtained = $SO_{3}$

Answer 2

Answer:

answer is option A 2...
