In a comparable solution of benzoic acid the freezing point is depressed only twice the predicted amount, indicating only a normal acid-base reaction. Further, a sulfuric acid solution of methyl mesitoate when poured into water gave mesitoic... 

You will perform three acid-base reactions. Before you begin, read the Procedure and make a prediction about the relative rates of these reactions. 

In this chapter, you will continue your study of acid-base reactions. You will find out how ions in aqueous solution can act as acids or bases. Then, by applying equilibrium concepts to ions in solution, you will be able to predict the solubility of ionic compounds in water and the formation of a precipitate. 

Just as the pH windows are useful in discussing the applicability of solvents as media for acid-base reactions, the potential windows (sometimes called electrochemical windows) are convenient to predict the usefulness of solvents as media for redox reactions. It is desirable that the potential windows are expressed based on a common (solvent-independent) potential scale, like the pH windows based on a common (solvent-independent) pH scale (Fig. 3.6). 

In a comparable solution of benzoic acid the freezing point is depressed only twice the predicted amount, indicating only a normal acid-base reaction. Further, a sulfuric acid solution of methyl mesitoate when poured into water gave mesitoic acid, while a similar solution of methyl benzoate similarly treated did not.534 The AacI mechanism is also found when acetates of phenols or of primary alcohols are hydrolyzed in concentrated (more than 90%) H2SO4 (the mechanism under the more usual dilute acid conditions is the normal Aac2).535... 

That the entropy change is unfavourable could be confidently predicted, given the presence of two moles of gas on the left-hand side. As the temperature is increased, the TAS" term becomes more important neglecting the small temperature dependence of AH° and A5°, it can be easily shown that AG° will become zero at about 850 K, at which temperature the decomposition of the complex should be complete. Such decomposition can be achieved at lower temperatures if the partial pressure of ammonia is kept low, by pumping. Most thermal decompositions-which are often the reverse of acid-base reactions (see Section 9.2) - are entropy-driven. All substances containing chemical bonds can be decomposed by heating to a sufficiently high temperature. 

The Laplacian of the electron density plays a dominant role throughout the theory.191 In addition, Bader has shown that the topology of the Laplacian recovers the Lewis model of the electron pair, a model that is not evident in the topology of the electron density itself. The Laplacian of the density thus provides a physical valence-shell electron pair repulsion (VSEPR) basis for the model of molecular geometry and for the prediction of the reaction sites and their relative alignment in acid-base reactions. This work is closely tied to earlier studies by Bader of the electron pair density, demonstrating that the spatial localization of electrons is a result of a corresponding localization of the Fermi correlation hole. 

Acid-base reactions involve transfer of a hydrogen ion from the acid to the base. In order to predict the products of an acid-base reaction, you first have to identify which is the acid and which is the base. Then, you just move an H+ ion from the acid to the base. This converts the acid into its conjugate base and the base into its conjugate acid. So, any acid-base reaction has two acids and two bases. There is one acid and one base on the reactant side, and the conjugate acid and the conjugate base on the product side.
