Magazine Problem 1
What is the pH range of human blood? How is human blood maintained in this pH range?
Problem 2
What is a buffer? How does a buffer work? How does it neutralize added acid? Added base?
Problem 3
What is the common ion effect?
Problem 5
What is the pH of a buffer when the concentrations of both buffer components (the weak acid and its conjugate base) are equal? What happens to the \(\mathrm{pH}\) when the buffer contains more of the weak acid than the conjugate base? More of the conjugate base than the weak acid?
Problem 6
Suppose that a buffer contains equal amounts of a weak acid and its conjugate base. What happens to the relative amounts of the weak acid and conjugate base when a small amount of strong acid is added to the buffer? What happens when a small amount of strong base is added?
Problem 8
What factors influence the effectiveness of a buffer? What are the characteristics of an effective buffer?
Problem 9
What is the effective pH range of a buffer (relative to the \(\mathrm{pK}_{\mathrm{a}}\) of the weak acid component)?
Problem 10
Describe acid-base titration. What is the equivalence point?
Problem 11
The pH at the equivalence point of the titration of a strong acid with a strong base is \(7.0 .\) However, the \(\mathrm{pH}\) at the equivalence point of the titration of a weak acid with a strong base is above \(7.0 .\) Explain.
Problem 15
The titration of a diprotic acid with sufficiently different \(\mathrm{p} K_{\mathrm{a}^{\prime}}^{\prime}\) displays two equivalence points. Why?
