Question

Why KCL gives a white prepitate with AgNO3 solution but CCL4 does not. why?

Answer 1

Explanation:

These Cl- ions combine with Ag+ ions of AgNO3 solution to form a white precipitate of AgCl. Whereas, CCl4 is a covalent compound and thus donot furnish Cl- ions in solution and hence donot form a white ppt. with AgNO.

Answer 2

Answer:

NaCl is an ionic compound.So, it ionizes into Na+ and Cl- ions in solution.These Cl- ions combine with Ag+ ions of AgNO3 solution to form a white precipitate of AgCl.Whereas, CCl4 is a covalent compound and thus donot furnish Cl- ions in solution and hence donot form a white ppt. with AgNO3.

NaCl → Na+ + Cl−AgNO3 → Ag+ + NO3−Ag+ + Cl− → AgCl                

 (white ppt.)
