प्रश्न
Distinguish by a chemical test sodium hydroxide solution and ammonium hydroxide solution.
Advertisements
उत्तर १
These salts can be distinguished by using metal cations like calcium. When we add calcium salt to sodium hydroxide and ammonium hydroxide, then a white curdy ppt. is formed only in the case of sodium hydroxide.
उत्तर २
With sodium hydroxide solution Ca(NO3)2 sol. gives a fine, milky white precipitate of Ca(OH)2 which is insoluble in excess of NaOH.
\[\ce{Ca[NO3] + 2NaOH -> \underset{milky white ppt}{2NaNO3} + Ca[OH]2\downarrow}\]
Whereas ammonium hydroxide solution with calcium nitrate solution Ca[NO3]2 has no reaction.
