A buffer solution is made that is 0.477 M in HF and 0.477 M in NaF. If K, for HF is 7.20 x 10 *, what is the pH of the buffer solution? pH = Write the net ionic equation for the reaction that occurs when 0.108 mol HCI is added to 1.00 L of the buffer solution. (Use the lowest possible coefficients. Omit states of matter. Use H3 0 instead of H)
