ACTTR Inc. - Understanding Spectrophotometer (3) Internal Structure

SOLVED: For the determination of an equilibrium constant, students monitored absorbance on a spectrophotometer. What does the measured absorbance indicate? - pH of the product - pKa of the acid - Temperature of the acid - Concentration of the product Question (5 points): A student titrated an unknown weak acid against a strong base added from a buret and determined the pH at the half-equivalence point. The pH at the half-equivalence point was 2.5. These results indicate that the pKa of the unkn
