On reacting zinc chloride with silver nitrate, solution turns milky white.

Reason:
Following reaction occurs in present system:

ZnCl2 (aq)   +    2AgNO3 (aq)     →     Zn(NO3)2    +    2AgCl↓
                                                                                       (white ppt.)

The solubility of AgCl in water is extremely poor. Infact, it is a sparingly soluble salt. Hence, it will get precipitate out. Colour of AgCl is white, hence the solution appears to be milky white. 

Answer: A white precipitate of silver chloride is formed in the above reaction.

Explanation:

Double displacement reaction is defined as the chemical reaction in which exchange of ions takes place.

When an aqueous solution of zinc chloride reacts with an aqueous solution of silver nitrate, it leads to the formation of aqueous solution of zinc nitrate and a solid silver chloride.

The chemical equation for the reaction of zinc chloride and silver nitrate follows:

[tex]ZnCl_2(aq.)+2AgNO_3(aq.)\rightarrow Zn(NO_3)_2(aq.)+2AgCl(s)[/tex]

A white precipitate of silver chloride is formed in the above reaction.
