Let’s compare two monoprotic acids: one strong (nitric, HNO3, pKa = -1.60) and one weak (acetic, CH3COOH, pKa = 4.79).

a. [4 points] Sketch an alpha diagram for each of the acids.

b. [6 points] Use your alpha diagram to predict the percentage of undissociated acid for each at the following pH values: 0.1, 3, 4.3, 6, and 13. After estimating the fractions with your diagram, check your values by calculating the exact value.

c. [4 points] Explain the difference in pKa values (and the percentage dissociated in parts a and b) for nitric acid and acetic acid. In your explanation, include and underline the following terms: pH, H+ concentration, strong/weak acid, and Le Chatelier’s Principle.

Make a list of the anions of the six strong monoprotic acids discussed in lecture. These anions are said to have no effect on the pH of an aqueous solution. The same is true for solutions of strong bases - their conjugate acids (which are Group 1 or Group 2 cations) are very weak acids, and therefore, have virtually no effect on the pH of the solution. 4. Make a list Group 1 and Group 2 cations, and note that...

Consider a monoprotic weak acid (HA) that is titrated with a strong base. What is the relationship between the strength of the weak acid and the pH of the solution at the equivalence point?  There is no relationship between the strength of the acid and the pH at the equivalence point. The pH at the equivalence point is always 7 in an acid base titration. The weaker the acid, the higher the pH at the equivalence point. The stronger the...

Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency to ionize (i.e., the ionic strength) of a weak acid or base can be quantified in several ways including Ka or Kb, pKa or pKb, and percent ionization. Part A Pyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also a component of cigarette smoke. Pyridine ionizes in water as follows: C5H5N+H2O⇌C5H5NH++OH− The...

Unlike strong acids and bases that ionize completely in solution, weak acids or bases partially ionize. The tendency of a weak acid or base to ionize can be quantified in several ways including Ka or Kb, pKa or pKb, and percent ionization*. *This assumes that species of equal concentrations are being compared as percent ionization is affected by concentration. Part A Pyridine is a weak base that is used in the manufacture of pesticides and plastic resins. It is also...
