Answer: (D) 3. \textbf{Answer:} (D) 3 \textbf{Solution:} Barium hydroxide is a strong electrolyte and dissociates completely in dilute aqueous solution: One formula unit produces 3 ions (one and two ).
- A.0
- B.1
- C.2
- D.3✓
Correct Answer
(D) 3
Solution & Explanation
\textbf{Answer:} (D) 3 \textbf{Solution:} Barium hydroxide is a strong electrolyte and dissociates completely in dilute aqueous solution: One formula unit produces 3 ions (one and two ). For complete dissociation the van't Hoff factor equals the number of particles produced, so .
