1. Enough of a monoprotic acid is dissolved in water to produce a 0.0126 M solution. The pH of the resulting solution is 6.38. calculate the Ka for the acid
2. Given that Ka for HBrO is 2.8 x 10^-9 at 25 deg C, what is the value of Kb for BrO- at 25 deg C?
3. Given that Kb for (CH3)2NH is 7.4 x 10 ^-4 at 25 deg C, what is the value of Ka for (CH3)2NH+ at 25 deg C?
4. HClO is a weak acid (Ka= 4.0 x 10^-8) and so the salt NaClO acts as a weak base. What is the pH of a solution that is 0.081 M in NaClO?
5. NH3 is a weak base (Kb= 1.8 x 10^-5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.032 M in NH4Cl?
