The `Ew` of an element is `13`. It forms an acidic oxide which `KOH` forms a salt isomorphous with `K_(2)SO_(4)`. The `Aw` of element is
a. `13`, b. `26`, c. `52`, d. `78`

A

13

B

26

C

52

D

78

Text Solution

Verified by Experts

The correct Answer is:
D
`K_(2) MSO_(4)` and `K_(2)SO_(4)` are isomorphous. Valency of `S` and `M` should be same `= 6`
Atomic weight `= Ew xx` Valency `= 13.00 xx = 78`
