A solution that is 0.500 M HF and 0.240 M NaOH reacts to produce a mixture with what pH? The pKa of HF is 3.20.
Hint: This is two reactions. The first involves a strong base with a weak acid —it will be quantitative. The second is an equilibrium reaction, the winner of the first reaction reacts with water. The second gives you the pH.
Please show all steps.
