Question

An analytical chemist is titrating 

129.9mL

 of a 

0.5200M

 solution of hydrazoic acid 

HN3

 with a 

0.2100M

 solution of 

NaOH

. The 

pKa

 of hydrazoic acid is 

4.72

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

241.9mL

 of the 

NaOH

 solution to it.

 

Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of 

NaOH

 solution added.

 

Round your answer to 

2

 decimal places.
