Distinguish between Lead nitrate and copper nitrate. 

Answer»

Lead nitrate is dissolved in water and then sodium hydroxide solution is added, a white precipitate is obtained, which is soluble in excess of sodium hydroxide.

Pb(NO3)2 + 2NaOH → Pb(OH)2 + 2NaNO3

Copper nitrate is dissolved in water and sodium hydroxide solution is added, a light blue precipitate of copper hydroxide is obtained.

Cu(NO3)2 + 2NaOH → Cu(OH)2 + 2NaNO3
