Question

Why does nacl gives a white precipitate with agno3 solution but ccl4 does not?

Answer 1

CCl4 is covalent - so its solution does not have any Cl(-) ions. Nacl reacts with AgNO3 to form AgCl(a white precipitate) This happens because there are free Cl- anions as NaCl is ionic. But CCl4 is covalent and doesn''t ionise so doesn''t give any precipitate.

Answer 2

ANSWER :

In 1st case NaCl and AgNO3 both are ionic compound..so they will react and form a white precipitate of AgCl in 2nd case AgNO3 is ionic but CCl4 is not ionic, so they will not react and no precipitate will be formed.
