(Bronsted-Lowry theory allows a substance to be either an acid or a base depending upon its interaction.) Conjugate Pairs: The two species with an A in them are called conjugate pairs. After the H+ has gone fro
Step 2:Use the Henderson-Hasselbalch equation to calculate the relative quantities of the acid and conjugate base. Vocabulary and Equations for Finding the Predominant Form of an Acid or Base Conjugate Acid/ Base:When a weak acid loses a proton, it turns into its "conjugate ...
Is H2SO4 an acid or a base? How do you know? How do you determine the formula for the conjugate base of an acid? Identify the acid and the base in the following reaction: HF(aq) + OH-(aq) F-(aq) + H2O(l). How would you test a solution to find out if it is acidic or ...
Calculate the pH of a buffer that contains the following acid and conjugate base concentration of: HNO_2 = 0.029; NO_2^- = 0.065 The pKa of HNO_2 = 3.33. What is the pH of an aqueous solution of acetic acid (pKa = 4.76) if the ratio of conjugate base to conj...
[HA] is the concentration of the original acid and [A-] is its conjugate base. At the equivalence point, enough base has been added to completely neutralize the acid, so the at the half-equivalence point, the concentrations of acid and base are equal. Therefore log ([A-]/[HA]) = ...
Read the problem, and write down the information that is given. In a problem that involves calculating the Kb from the Ka, you are usually given the Ka and the Kw. For example, you may be asked to calculate the Kb of the chloride ion. The given Ka of the conjugate acid of the chlo...
dioxide, which in turn produces acid rain (SO2). Trioxosulfuric acid is a colourless, odourless liquid that emits a noxious sulphur odour. Tissues and metals are both corroded by them. Some of the properties that distinguish it are conjugate acid of hydrogen sulfite and sulphur oxoacid…read ...

Start with the Henderson-Hasselbach equation, use it to find ratio of acid and conjugate base. You know sum of their concetrations - 10 mM. That gives you two equations in two unknowns, solve and you know concentrations of both acid and conjugate base. Then it is just a matter of ...
to adenine13. The A:T base pair, with two hydrogen bonds, is therefore replaced by the Z:T base pair that has three hydrogen bonds, as in the G:C base pair (Fig.1). This feature, combined with an unusually high GC content of S-2L genome, explains its exceptionally high melting ...
