In the refining of silver, the recovery of silver from silver nitrate solution involved displacement by copper metal.
Answer 2AgNO3 (aq) + Cu (s) → Cu(NO3)2 (aq) + 2Ag (s) Silver Nitrate + Copper → Copper Nitrate + Silver

A solution of potassium chloride when mixed with silver nitrate solution, an insoluble white substance is formed.
KCl (aq) + AgNO3 (aq) → AgCl (s) + KNO3 (aq) It is a double displacement and precipitation reaction.

Will CCl4 give white precipitate of AgCl on heating it with silver nitrate? Give reason for your answer.
CCl4 will not give the white precipitate of AgCl on heating it with silver nitrate. This is because the chlorine atoms are covalently bonded to carbon in CCl4. To obtain...

10 gm of silver nitrate solution is added to 10 gm of sodium chloride solution. What change in mass do you expect after the reaction and why?
No change in mass will take place because mass can neither be created nor destroyed in a chemical reaction as law of conservation of mass states.

A copper coin was kept dipped in silver nitrate solution for a few hours/days.
Copper is more reactive than silver. Hence, it displaces silver from the silver nitrate solution according to the given reaction. Cu(s) + 2AgNO3(aq) --------> Cu(NO3)2(aq) + 2Ag(s) Copper Silver nitrate ...
