Passage

Read the passage given below and answer the questions that follows :

The oxidation state of the elements in the pure state = 0. The equivalent wt. of the element

E = Atomicwtoftheelementx where x = valency

The equivalent wt. of any compound = sum of the equivalent wt. of component elements or ions.

By using this relation we can calculate the equivalent wt. of any acidic and basic oxide.
