Question

We have 100 mL of a buffer that is made to be 0.1M HF and 0.075M NaF. What is the pH of the buffer? What is the pH of the buffer after 0.0015 moles of HNO3 has been added? What if the pH of the buffer if I add 0.0015 moles of NaOH instead of acid? What would the concentration of the HNO3 (from the previous question) if the 0.015 mole acid were contained in 1.0 mL of HNO3 solution?
