why ammonium nitrate and ammonium carbonate DO NOT produce ammonia gas when react with alkali?
meanwhile, ammonium chloride can produce ammonia gas when react with alkali........

Your sharing is kindly appreciate.
Thank you very much!!

Is it? May i know which reference u refer?
Because ammonium nitrate and ammonium carbonate contain ammonium ion. Thus when ammonium ion mixed with sodium hydroxide and is heated, ammonia gas is produced.

i'm using pelangi focus chemistry reference book.

Ya..i checked..Cant figure it out..
But another reaction that can produce ammonia gas is reacting the base and ammmonium salt to produce ammonia gas.
For eg: A mixture of calcium hydroxide is heated together wth ammonium sulphate solid, ammonia gas is produced.

[Jong Kah Yin]

Any base / alkali can react with ammonium salts / ions will produce ammonia gas and water upon heating

Ionic equation for reaction involving any alkali and ammonium ions

NH₄⁺    +   OH^-    ->   NH₃  +  H₂O

Thanks Mr.Jong..

[Ling Teck Ping]

so means that we can ask students to ignore the sentence in the reference book because all type of ammonium salts can react with base/alkali to produce NH3?

thanks,Mr Jong and Mr Chai

which Pelangi book? Year ? what page ?

You can view the latest version Hot Super Chemistry(Pelangi), Chapter8 (salt).
