标题[化学] 酸硷比较
时间Mon Jun 15 19:48:37 2009
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 硷 中 硷 酸 酸 中 弱硷
酸性大小：
NH4Cl(aq) > CH3COOH(aq) > CH3COONH4(aq) > CH3COONa(aq) > NH3
我会了!谢谢大家:)
