Ammonia + Potassium hydroxide

NH4+(aq) + OH-(aq) -->NH3(aq)+H2O(l)
這是一平衡體系,反應為什麼要加熱?
因為加熱會降低NH3溶解度,使它成由氣體形式釋出!
平衡位置向右移
所以 ammonium compound decompose upon heating with large amount of hydroxide ions致於你的問題,Will ammonia solution also decompose if heated with potassium hydroxide solution and what will be the observable change if there is a reaction?
只有ammonium compound decompose的說法,沒有ammonia solution decompose的說法
因為ammonia solution本來的主要成份就是NH3(aq),加熱它就釋出來了
所以加入 potassium hydroxide solution ,可以說是多餘的..

Ammonia can also act as an acid, yielding amide ion NH2(-).
But eqm. constant is just too small that, any water present would react as acid first. Even with solid KOH & anhydrous NH3, the reaction's still unlikely to occur.
