CH3COONa溶液中c(CH3COOH)与c(OH+)大小
CH3COONa溶液中c(CH3COOH)>c(H )如何确定?
在Ph=5.6的CH3COOH与CH3COONa混合溶液中,c(Na+)>c(CH3COOH~
CH3COOH溶液中c(CH3COO-)小于CH3COONa溶液中c(CH3COO-)对么
CH3COONA加水稀释溶液,溶液中c(CH3COOH)C(OH-)/c(CH3COO-)怎么变
CH3COONa溶液中c(CH3COOH0与c(OH+)大小为c(CH3COOH)
CH3COONa溶于水后溶液中c(CH3COOH)>c(H )如何确定?
向ch3coona溶液中加入适量ch3cooh溶液,得到的酸性混合溶液为什么c(ch3coo-)>c(h+)
向CH3COONa溶液中滴加稀HCl至中性,所得溶液中c(Cl-)>c(Na+)>c(CH3COOH)怎么错了啊?
ch3cooh溶液加入少量ch3coona晶体时会引起:溶液中的c(h+)减弱我是这么想的:ch3cooh----ch3coo- + h+ch3coona中:ch3coo- + h+ -----ch3cooh 所以c(h+)不变那里出错呢
CH3COONa水解.其溶液中[H+]>[CH3COOH]吗?
浓度相等的CH3COOH和CH3COONa溶液等体积混合后的溶液中:为什么C(CH3COO-)+C(CH3COOH)=2C(Na+)
在0.1mol/l CH3COONa溶液中,c(OH-)>c(CH3COOH)+c(H+)是正确的吗,为什么
pH = 5.6的CH3COOH与CH3COONa混合溶液中,c(Na+)>c(CH3COO-)怎么做啊?详解…
CH3COONa溶液中C(OH-)与C(CH3COOH)为什么不相等?看到别人问相等吗?我来问个为什么不相等.
1 CH3COOH与CH3COONa等物质的量混合配置成溶液,PH为4.7,下列说法中错误的是 ( )A CH3COOH的电离作用大于CH3COONa的水解作用B CH3COONa的水解作用大于CH3COOH的电离作用C CH3COOH的存在抑制了CH3COONa的水
CH3COONa溶液中C(OH-)与C(CH3COOH)相等吗?(CH3COO-)+(H+)=CH3COOH,这样看是相等的但水中的OH-要不要算进去?
相同浓度的下列溶液:CH3COONH4、CH3COONa, CH3COOH中,C(CH3COO- )由大到小的顺序是为什么?
