Transcribed Image Text:A chemist titrates 170.0 mL of a 0.6472 M cyanic acid (HCNO) solution with 0.6584M KOH solution at 25 °C, Calculate the pH at equivalence. The p K of
cyanic acid is 3.46.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
