उत्तर
If Sodium Chloride is added to Silver Nitrate Solution then,
(a) A white coloured precipitate of silver chloride is formed.
(b) The reaction is double displacement reaction.
(c) \[\ce{AgNO3_{(aq)} + NaCI_{(aq)}-> NaNO3_{(aq)} + AgCI_{(s)}}\]
Where: \[\ce{AgNO3_{(aq)}}\] = Silver nitrate
\[\ce{NaCI_{(aq)}}\] = Sodium Chloride
\[\ce{NaNO3_{(aq)}}\] = Sodium Nitrate
\[\ce{AgCI_{(s)}}\] = Silver Chloride
