So.. the closer to 0 or 1 Ka is the stronger the acid and when you take pka =-log Ka.What i don t know is:Since pka plus pkb equals 14 and ph and poh equals,again , 14What if ph is equal to pka ?What if ph is smaller than pka?What if ph is bigger than pka? Logged ...
log k w pka + pkb = pkw list of pka value of acids acid ionisation constants (k a ) and pk a values at 25℃ compound formula ka value pka value acetic acid ch 3 cooh 1.7 x 10 -5 4.75 benzoic acid c 6 h 5 cooh 6.3 x 10 -5 4.20 boric acid h 3 bo 3 5.9 x 10 -10 ...
In addition to using pKa to gauge the strength of an acid, it may be usedto select buffers. This is possible because of the relationship between pKa and pH: pH = pKa+ log10([A-]/[AH]) Where the square brackets are used to indicate the concentrations of the acid and its conjugate b...

1.On the elemental electronegative,bondid electron number and pz eletron number of atoms,one new molecular topological index (4X) is developed for research on the Pka values for 21 substituted phenols and the Pkb values for 22 substituted benzenne amines in this paper.结果表明,4X具有良好的结构...
结果表明,4X具有良好的结构选择性和性质相关性,可用于预测其它取代酚酸性PKa值和取代苯胺碱性PKb值。 更多例句>> 3) pKa value pKa值 1. OBJECTIVE The solubility in different solvents,the oil/water detached coefficient and pKa value of genistein were determined for the study of its absorption in viv...
b) 微物种使用三联体表示, 第1个圈表示羧酸基团的氧原子, 第2个圈表示中间的氮原子, 第3个 圈表示距离羧酸基团最远的氮原子, 其中实心圈代表未解离状态, 空心圈代表解离状态 字有歧义,不标准, 或者是印刷错误等; (2) 错误的数 值, 比如上面苯酚的例子, 或者pKa数据的印刷错误, 使用Ka或pKb(碱)代替pKa...
What do the values 0.7 and 14 on the pH scale mean? Be specific regarding the relationship of H+ and OH-ions, as well as the exponent values. What is the potential hydrogen (pH) of water value? A. How many H+ are there per 555 million water molecule at room temperature, 25...
Answer and Explanation:1 Among the given compounds the one with the highest acidic strength (i.e., the best acid) is compoundG(p-nitro-benzoic acid) as it has the acidic... Learn more about this topic: pKa of Acids & Functional Groups | Overview & Examples ...
−9 m frequently asked questions on ka chemistry q1 what is pka and ka? ka is the acid dissociation constant. pka is simply the -log of this constant. similarly, kb is the base dissociation constant, while pkb is the -log of the constant. the acid and base dissociation constants are ...
