A buffer solution is made that is 0.389 M in HCN and 0.389 M in NaCN. If K, for HCN is 4.00 x 10-10 what is the pH of the buffer solution? pH = Write the net ionic equation for the reaction that occurs when 0.079 mol HBr is added to 1.00 L of the buffer solution. (Use the lowest possible coefficients. Omit states of matter. Use H30 instead of H*)
