प्रश्न
Shravani was performing inorganic qualitative analysis of a salt. To an aqueous solution of that salt, she added silver nitrate. When a white precipitate was formed. On adding ammonium hydroxide to this, she obtained a clear solution. Comment on her observations and write the chemical reactions involved.
उत्तर
- When silver nitrate (AgNO3) is added to an aqueous solution of salt sodium chloride (NaCl), a white precipitate of silver chloride (AgCl) is formed.
\[\ce{\underset{Sodium chloride}{NaCl_{(aq)}} + \underset{Silver nitrate}{AgNO_{3(aq)}} -> \underset{(White ppt)}{\underset{Silver chloride}{AgCl_{(s)}}} + \underset{Sodium nitrate}{NaNO_{3(aq)}}}\] - On adding ammonium hydroxide (NH4OH) to this, the white precipitate of silver chloride gets dissolved and thus, a clear solution is obtained.
\[\ce{\underset{White ppt}{AgCl_{(s)}} + \underset{Ammonium hydroxide}{2NH4OH_{(aq)}} -> \underset{(Colourless)}{\underset{Diamine silver chloride}{Ag(NH3)2Cl_{(aq)}}} + 2H2O}\]
