Chemical Properties of Acids and Bases:Acids and bases play an important role in our daily lives. Many of the foods we consume are acidic in nature. Lemons and oranges contain citric acid, and vinegar is an acetic acid solution. Baking soda is a common household item and it’s a base. ...
The Meaning of Ka, the Acid Dissociation Constant For the ionization of an acid, HA: HA(aq) + H2O(l) H3O+(aq) + A-(aq) Since the concentration of water is high, and does not change significantly during the reaction, it’s value is absorbed into the constant. Therefore: The stronger...
acid and base catalysisThe word amphoteric is derived from the Greek amphi meaning both and used to describe surfactants which have both a positive (cationic) and a negative (anionic) group. Sometimes the phrase ampholytic is used. The nomenclature of some amphoterics has been confused in the ...
Carboxylic acids are weak acids (see the chapter on acids and bases), meaning they are not 100% ionized in water. Generally only about 1% of the molecules of a carboxylic acid dissolved in water are ionized at any given time. The remaining molecules are undissociated in solution. We prepare...
Assess the relative strengths of acids and bases according to their ionization constants Rationalize trends in acid–base strength in relation to molecular structure Carry out equilibrium calculations for weak acid–base systemsThe relative strength of an acid or base is the extent to which it ionize...

8.4 – pH Scale When dealing with acids and bases in chemistry we often deal with very small concentrations of [H+] and [OH-] ions that range from 1x100 to 1x10-14 Instead of using these small values, we break it down into the log10 scale from 0-14 If [H+] = 1x100 M, then...
Are the strong bases also strong electrolytes? Explain. Give an example of a weak acid and an example of a strong acid. What is the difference between them in terms of reactivity? What are the structural differences in acids and bases? Wha...
The buffering capacities of weak acids and weak bases are maximal at their pK values. Thus, monoaminomono-carboxylic acids exhibit their greatest buffering capacities in the two pH ranges near their two pK′ values, namely, pH 2.3 and pH 9.7 (Figure 2-7). Neither these amino acids nor the...
