A Buffer sоlutiоn оf HCN аnd NаCN wаs prepared using 0.250 M HCN and 0.250 M NaCN. The acid ionization constant (Ka) of HCN is 4.9 x 10-10 and the pH of the buffer solution was 9.31. What will be the pH of the solution after the addition of 0.0100 moles of NaOH to 1 L of buffer solution? (Assume there is no change in volume)Report your answer to 3 significant figuresHCN(aq) ↔ H+(aq) + CN-(aq)HCN(aq) + NaOH(aq) --> H2O(l) + NaCN(aq)
