- How do you calculate the pH of a solution containing a weak acid or a weak base? Please write down the general formula for finding the H3O+ ion concentrations in case of a weak acid
- Please explain the common-ion effect in terms of Le Châtelier. You might want to use the general chemical equation for an acid ionization HA + H2O ↔ A- + H3O+ to help you explain the phenomenon.
- How do you calculate the degree of ionization?
- Please explain how you would choose a certain acid/base pair in order to make up a buffer of a certain pH. Which formula would be handy to use in this case? (2 points)
- What happens to the pH of a buffer if you add
- an acid? ______________
- a base? ______________
- Please calculate the pH of a) a 0.1 M solution of acetic acid (HOAc) and b) a 0.001 M solution of acetic acid. The Ka for acetic acid is 1.7 x 10-5. What do the results show in terms of dilution and pH of a weak acid or a weak base? (2 points)
