Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

An analytical chemist is titrating 179,5 ml of a 0.5300M solution of formic acid (H,CO,) with a 1.100M solution of KOH. The pK of formic acid is 3.74.
Calculate the pH of the acid solution after the chemist has added 92.63 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.
