Question

What reaction can I do to distinguish BaCl2, NaCl and LiCl?

Answer 1

1) BaCl₂ + H₂S0₄   reacts to give Ba₂SO₄ and HCl where Ba₂SO₄ gives a white precipitate which is insoluble in aqueous solution

but NaCl + H₂SO₄ gives Na₂SO₄ which is highly soluble

this way we can distinguish them

LiCl + CaCO₃ reacts to give LiCO₃ and CaCl₂ where LiCO₃ is sparingly soluble in aqueous solution

on the other hand NaCl + CaCO₃ reacts to give Na₂CO₃ where Na₂CO₃ is completely soluble in aqueous solution

this way we can distinguish them
