关于平衡常数equilibrium constant （Ka)的问题
俺做题目的时候搞了半天没搞懂 摆脱那位大大帮忙解答下
HF + H2O H3O+ + F- Ka = 7.2 x 10-4
HS- + H2O H3O+ + S2- Ka = 1.3 x 10-13
CH3COOH + H2O H3O+ + CH3COO- Ka = 1.8 x 10-5
(i) Which is the strongest acid?
(ii) Which is the weakest acid?
(iii)What is the conjugate base of the acid HF?
(iv) Which acid has the weakest conjugate base?
(v) Which acid has the strongest conjugate base?

关于平衡常数equilibrium constant （Ka)的问题俺做题目的时候搞了半天没搞懂 摆脱那位大大帮忙解答下 HF + H2O H3O+ + F- Ka = 7.2 x 10-4HS- + H2O H3O+ + S2- Ka = 1.3 x 10-13CH3COOH + H2O H3O+ + CH3COO- Ka = 1.8 x 10-5(i)
你在国外读书吧?:)
(i)HF is the strongest acid since it has the largest value of Ka.HF酸性最强,因为它平衡常数最大.
(ii)HS- is the weakest acid since it has the smallest value of Ka.HS- 酸性最弱,因为它平衡常数最小.
(iii)F- is the conjugate base of HF.F-是HF的共轭碱.
(iv)HF(the strongest acid) has the weakest conjugate base.HF是最强的酸,它有最弱的共轭碱.
(v)HS- (the weakest acid) has the strongest conjugate base.HS-是最弱酸,它有最强的共轭碱.
以下是解答这五道题的思路依据：
(i)(ii)The lager the value of Ka,the stronger the acid.平衡常数越大,酸性越强.
(iii)Every acid has a conjugate base,formed by removing a proton from the acid.每种酸都有一个与之对应的共轭碱,此共轭碱的化学式是将原来那种酸的化学式去掉一个质子（氢离子）.
(iv)(v)The stronger an acid,the weaker is its conjugate base; the stronger a base,the weaker is its conjugate acid.一种酸的酸性越强,它的共轭碱就越弱；一种碱的碱性越强,它的共轭酸就越弱.

equilibrium 高中化学问题.关于平衡常数的 关于平衡常数equilibrium constant （Ka)的问题俺做题目的时候搞了半天没搞懂 摆脱那位大大帮忙解答下 HF + H2O H3O+ + F- Ka = 7.2 x 10-4HS- + H2O H3O+ + S2- Ka = 1.3 x 10-13CH3COOH + H2O H3O+ + CH3COO- Ka = 1.8 x 10-5(i) rapid equilibrium 求助,关于平衡常数的问题,紧急!请问一下电离平衡常数、水解平衡常数、溶解平衡常数的计算表达式都 如何算化学里的equilibrium constant（即平衡常数）如题,知道公式但不是很理解.再请问平衡常数有没有固定单位?请给出具体问题具体例子. 关于无机化学平衡常数的一个题 关于大学普通化学平衡常数的原理? 可逆反应CO+H2O CO2+H2 计算平衡常数计算平衡常数时,水的浓度要计算进去吗? 关于平衡常数表达式书上说,液体不写进平衡常数表达式,那么乙酸乙酯水解的平衡常数怎么写?全是液体 计算反应CO2+H2=CO+H2O在873K的标准平衡常数 CO2+H2=CO+H20达平衡时,其平衡常数表达式Kc= 2NH3(g)+CO2(g)=CO(NH2)2(L)+H2O(l)的化学平衡常数表达式 已知在一定温度下：C(s)+CO2(g) 2CO(g)平衡常数K； .已知在一定温度下：C(s)+CO2(g) 2CO(g)平衡常数K； C(s) + H2O(g) CO(g)+H2(g) 平衡常数K1； CO(g)＋H2O(g) H2(g)＋CO2(g) 平衡常数K2 ,则K、K1、K2之间的关系是： Shayton Equilibrium什么意思 equilibrium predict什么意思 equilibrium-partitioning是什么意思 equilibrium concentration是什么意思
