- One of the following statements is incorrect Select one: O Back-titration is required when the rate of the reaction slow. O A standard solution should react completely with the analyte without a definite chemical equation. Standardization is required when the titrant solution molarity is approximate. O A primary standard should be highly pure, has atmospheric stability and absence of hydrated water. O Titration error is the difference between equivalence point volume and end point volume.E Determination of an Equilibrium Constant (25 points) product Fe(SC Concentration (C) of the product.

Two samples wereprovided, labelled C and D (Control and Diseased serum).The students decided to follow the loss of absorbance of NADH in an appropriate assay buffercontaining pyruvate as the substrate. Q1 (a) By examining the absorbance spectra(in the image attached) of both NAD+ and NADH below, comment why this approach is suitable strategy. Q1 (b). What would be the optimum wavelength at which they should measure absorbance? Give a reason for your answer. The students conducted the assay for LDH activity using the two serum samples. Each cuvette (path length 1 cm) contained 3ml of a suitable assay buffer (including pyruvate as substrate). 20 microlitres of either serum was added to the cuvette and the absorbance values…
