化学方程式:CH3COOH + NH3.H3O == CH3COONH4 + H2O
离子方程式:CH3COOH + NH3.H2O == CH3COO- + NH4+
要注意CH3COOH和NH3.H2O都是弱电解质,所以写离子方程式时不能拆。
CH3COONH4是强电解质,要拆。
CH3COOH + NH3.H3O == CH3COONH4 + H2O
离子方程式:CH3COOH + NH3.H2O == CH3COO- + NH4+ + H2O
1....CH3COOH+NH3.H2O=CH3COONH4+H2O
2...CH3COOH+NH3.H2O=NH4++CH3COO-+H2O
好!
