Question

An analytical chemist is titrating

132.3mL

 of a 

0.9400M

 solution of cyanic acid 

HCNO

 with a 

0.8000M

 solution of 

KOH

. The 

pKa

 of cyanic acid is 

3.46

.Calculate the pH of the acid solution after the chemist has added 

163.4mL

 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.
