The van't hoff factor (i) for a dilute aqueous solution of the strong electrolyte barium hydroxide is

A

0

B

1

C

2

D

3

Text Solution

Verified by Experts

The correct Answer is:
B
`Ba(OH)_(2)` is strong electrolyte, so its 100% dissociation occurs in solution
`Ba(OH)_(2)rarr Ba^(2+)(aq)+2OH^(-)(aq)`
Van.t Hoff factor = total number of ions present in solution i=3
