问题的提出铵盐溶液与碱溶液反应的原离子方程式,通常的写法有两种: ②一般认为,在加热条件下反应写成①,在室温条件下,将铵盐溶液与碱溶液混和,生成的NH_3在溶液中与水结合成NH_3·H_2O而不挥发出来。显而易见,在写②式时,仅考虑了温度因素,而设有考虑浓度因素。而我多年教学实践证明,达到一定浓度的铵盐溶
The problem of the proposed original ion equation of ammonium salt solution and alkali solution reaction, there are two common ways to write: 2 is generally believed that under the heating conditions, the reaction is written as 1, in the room temperature conditions, the ammonium salt solution and alkali solution mixed, generated NH_3 combines with water in solution to form NH 3 H 2 O without volatilization. Obviously, when writing formula 2, only the temperature factor was taken into account, and the concentration factor was considered. And my teaching practice for many years has proved that reaching a certain concentration of ammonium salts
