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:) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.129.77.5

41325，解離度可能要考慮吧?CH3COOH解離比NH4Cl少很多。
