- The equilibrium constant for the conjugate acid-base pair HIn+H2OH3O++In is 8.00 10-5. From the additional information in the following table, (a) calculate the absorbance at 430 nmand 600 nm for the following indicator concentrations: 3.00 10-4M,2.00 10-4M, 1.00 10-4M, 0.500 10-4 M, and 0.250 10-4M. (b) plot absorbance as a function of indicator concentration.One of the following statements is incorrect: O Titration error is the difference between equivalence point volume and end point volume O A primary standard should be highly pure, has atmospheric stability and absence of hydrated water O Back-titration is required when the rate of the reaction slow O A standard solution should react completely with the analyte with a definite chemical equation O tandardization is not required when the titrant solution molarity is approximate2- Ahmed has done four types of titrations of 1M and 50 ml for both acid and base (Conductometric Titration of Strong Acid with Strong Base , Potentiometric Titration of Weak Acid with Strong Base , Potentiometric Titration of Strong Acid with Strong Base and Conductometric Titration of Weak Acid with Strong Base ).
