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 the precipitate, it should be present in ionic form and for this, it is necessary to prepare the Lassaigne’s extract of CCl4.

When CCl4 is heated with AgNO3 solution, white ppt. of AgCl will not be formed. The reason being that CCl4 is a covalent compound, therefore, it does not ionize to give Cl- ions needed for the formation of ppt. of AgCl.

No. CCl4 is a completely non-polar covalent compound whereas AgNO3 is ionic in nature. Therefore they are not expected to react and thus a white ppt. of silver chloride will not be formed.

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.

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 ...
