11 . B The definition and properties of a catalyst are discussed in the section on factors affecting the reactio ...

Chapter 13 Acids and Bases Many important reactions in chemical and biological systems involve two classes of comp ...

Definitions Three different definitions of acids and bases exist. The Brønsted-Lowry definition is the most common, ...

A Brønsted-Lowry acid is a species that donates protons, while a Brønsted-Lowry base is a species that ...

Nomenclature of Acids The name of an acid is related to the name of the parent anion (the anion that ...

Properties of Acids and Bases Acids and bases are compounds with unique properties and behaviors. In general, ...

H 2 O(l) H+ (aq) + OH− (aq) This dissociation is an equilibrium reaction and is therefore described ...

It should also be pointed out that even though we have written acid-base reactions so far as involving p ...

include NaOH (sodium hydroxide), KOH (potassium hydroxide), and other soluble hydroxides of Group IA and IIA metals. C ...

CONJUGATE ACIDS AND BASES REVISITED As mentioned above, a conjugate acid is defined as the acid formed wh ...

The equilibrium constant for this net reaction is Kw = [H+][OH−], which is the product of Ka and Kb. Thus, ...

We can approximate that 2.0 – x ≈ 2.0 since acetic acid is a weak acid, and only slightly dissocia ...

Polyvalence and Normality The relative acidity or basicity of an aqueous solution is determined by the relative ...

Salt Formation Acids and bases may react with each other, forming a salt and (often, but not always) water, ...

On the other hand, when a weak acid reacts with a strong base the solution is basic, due to the ...

Titration and Buffers Neutralization is an important concept in the performance of titrations. Titration (or more speci ...

Similarly, in the last part of the titration curve (when an excess of base has been added), the addition ...

equivalence point, a slight difference in pH between it and the endpoint translates to a minuscule difference in ...

A CLOSER LOOK The pH of blood is maintained within a small range (slightly above 7) by a bicarbonate buff ...
