The salt which responds to dilute and concentrated ( H ₂ SO ₄ ) is
Options
- A( CaF ₂ )
- B( B a (N O₃ )₂ )
- C( Na ₂ SO ₄ )
- D( Na ₃ PO ₄ )
Correct answer
B. ( B a (N O₃ )₂ )
Step-by-step solution
Reaction of ( Ba ( NO ₃ )₂ ) will ( H ₂ SO ₄ ) is a double displacement reaction in which precipitate of ( BaSO ₄ ) will be formed, therefore, reaction will proceed in forward direction even for low concentration of sulphuric acid. ( Ba ( NO ₃ )₂+ H ₂ SO ₄ BaSO ₄+2 HNO ₃ )
