[化學] 酸鹼比較

[clearfray (老虎奶油)]

Arrange the following aqueous solution(all 0.1M)
in the order of increasing acidity.

CH3COOH(aq)  CH3COONa(aq)  CH3COONH4(aq)  NH4Cl(aq)  NH3



我知道:

CH3COOH(aq)  CH3COONa(aq)  CH3COONH4(aq)  NH4Cl(aq)  NH3
    ↑         ↑  ↑         ↑  ↑      ↑ ↑      ↑
   弱酸        鹼  中         鹼  酸      酸 中      弱鹼

酸性大小：

NH4Cl(aq) > CH3COOH(aq) > CH3COONH4(aq) > CH3COONa(aq) > NH3


我會了!謝謝大家:)

推 doggy1130:樓上好像少了什麼= =
推 mimipig:XDDDDDDDDDD
→ Yeahwei:14325
→ missass:41325，解離度可能要考慮吧?CH3COOH解離比NH4Cl少很多。
→ dysphagia:少甚麼 少說明嗎 !
推 howchiu:是少了CH3COOH(aq) 你列了兩個CH3COONa(aq)
推 BioJacob:41325 +1
