44. During amperometric titration of acetaldehyde with 2,4-dinitrophenylhydrazine at a potential of -1.4 V relative to mercury, the following data were obtained:
Vtitrant, ml 0.2 0.25 0.35 0.45 0.53 0.61 0.69 0.90
I, μA 0 78 63 45 30 30 39 60
find the equivalence point and the aldehyde content if the titer of 2,4-dinitrophenylhydrazine for acetaldehyde is 5.6*10-6 g/ml.
