What are the conjugate acid-base pairs in the following equation? {eq}HCN(aq) + SO_4^{2-}(aq) \to CN^-(aq) + HSO_4^-(aq) {/eq} Conjugate Acid-Base Pairs: According to Brønsted-Lowry acid-base theory, a conjugate base is the chemical ...
The acid donates the proton and forms an anion which is called the conjugate base of the acid while the bases accept the proton in order to form the conjugate acid. The strength of the conjugate acid and conjugate base depends on the strength of acid and base. ...
An acid-base pair conjugate is related by one being a proton donator and the other a proton acceptor. We can use this relationship by solving the concentration of the hydrogen/hydronium ions present. Hydrogen ion concentration is the basis for the pH value of the solutio...
Conjugate acid-base pair : A single proton separates two molecular units. What Is Buffer Capacity and What Does It Mean? The amount of acid that buffers can absorb before breaking the capacity for adding strong acid is referred to as buffer capacity. When adding a strong acid, solutions wit...
Likewise, the ammonium ion is the conjugate acid of ammonia. Together, an acid with its conjugate base (such as HNO3 and NO3-) or a base with its conjugate acid (such as NH3 and NH4+) is referred to as a conjugate acid-base pair. Lewis Acids and Bases In the Brnsted-Lowry ...

What is a conjugated system? If you are referring to conjugate acids and bases, a conjugate acid is an acid that can donate a H+ in order to form a conjugate base. For example, HCl can donate it's H+ and create the conjugate base Cl-. On the other hand, a conjugate base would ...
where HA is the acid and A- is the conjugate base. Ka = [A-][H3O+] / [HA][H2O] This is used to calculate pKa, the logarithmic constant: PKA = – log10 Ka The larger the pKa value, the smaller the dissociation of the acid and the weaker the acid. Strong acids have a pKa of...
The pKa of acid is 5.The pH of a solution containing acid X and its conjugate base is 6.What is the ratio of the concentration of conjugate base to the concentration of acid?(conjugate base:acid) (A)1:1 (B)2:1 (C)5:1 (D)10:1 (E)20:1 反馈 收藏 有用 解析 免费查看答案及解...
Which of the following is not an acid-base conjugate pair? (a) H2S and OH- (b) H2CO3 and HCO3- (c) NH4+ and NH3 (d) H2O and OH- (e) none of the options 1. What is the conjugate base of HCO_3^-? Express your answer as a chemical formula. 2. What is the conjugate acid...
