What is the pH of 1L of buffer made from 0.6M HF and 0.54M NaF (pKa of HF = 3.45)? If 0.01M HCl is added (disregard change in volume), what is the new pH? If 0.01M NaOH had been added instead?
The pH of a buffer that is 0.860 M HF and 0.670 M KF is 3.03. Calculate the new pH if 1.45 g of NaOH were added to 800 mL of the buffer. Assume no change in solution volume. Perform neutralization first. pH should be 3.09
