The observed geometry reflects a compromise between two competing factors: 1) stabilization of the N lone pair in an orbital with significant s character favors pyramidalization (orbitals with s character are lower in energy), while 2) delocalization of the N lone pair into the aryl ring favors planarity (a lone pair in a pure p orbital gives the best overlap with the orbitals of the benzene ring system). Like phenols, aniline derivatives are highly susceptible to electrophilic substitution reactions. For which of the given acids, whose #pK_a# data are listed, will #pH# be HIGHEST at the equivalence point when titrated by #NaOH(aq)#?

This reason can also be considered for explaining why the aqueous solution of potassium bromide (KBr) is neutral with no acidic or alkaline properties. In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base. This means that an aqueous solution of such a compound will have the dissociated ions participate in acid-base (proton transfer) reactions with water molecules. HBr. Required fields are marked *. In a solution of a salt formed by the reaction of a weak acid and a weak base, to predict the pH, we must know both the Ka of the weak acid and the Kb of the weak base. When it reacts with an acid such as lemon juice, buttermilk, or sour cream in a batter, bubbles of carbon dioxide gas are formed from decomposition of the resulting carbonic acid, and the batter rises.
