An analytical chemist is titrating 69.9 mL of a 0.2200M solution of cyanic acid (HCNO) with a 0.8900M solution of KOH. The p K of cyanic acid is 3.46. Calculate the pH of the acid solution after the chemist has added 5.93 mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal places.

Question
![An analytical chemist is titrating 69.9 mL of a 0.2200 M solution of cyanic acid (\(HCNO\)) with a 0.8900 M solution of \(KOH\). The \(pK_a\) of cyanic acid is 3.46. Calculate the pH of the acid solution after the chemist has added 5.93 mL of the \(KOH\) solution to it.
*Note for advanced students:* you may assume the final volume equals the initial volume of the solution plus the volume of \(KOH\) solution added.
Round your answer to 2 decimal places.
\[ \text{pH} = \] [Input box]
There are two buttons next to the input box:
- A button with an X (likely for clearing the input).
- A button with a refresh icon (likely to reset the calculation).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa60cc6ce-11de-444a-af29-e9eb1b50e640%2Fadb8245e-6474-4de6-95c7-a7d291eaa51f%2F5wz2spr_processed.png&w=3840&q=75)
