Acid-Base Titration of a Weak Acid with a Strong Base: Determination of K. Introduction: You will be titrating a solution of a weak acid with 0.100 M NaOH, while monitoring the reaction using a pH meter. Weak acids have characteristic acid-ionization constants, K. The purpose of this lab is to use the titration to determine the value of this constant for the weak acid called “benzoic...

Please show all work, thanks.
A hydrocyanic acid buffer solution contains 0.84 M hydrocyanic acid (HCN) and 0.61 M of its conjugate base (CN). If a chemist adds 0.15 mol of nitric acid (HNO3), a strong acid, to 0.55 L of the buffer solution, what will be the final pH of the solution? (The pk of HCN is 9.21. Assume the volume of the added HNO3 is negligible.) 4.0
