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

A

2

B

3

C

0

D

1

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)+2OH_((aq))^(-)`
Van.t Hoff factor = total number of ions present in solution i = 3
