An end point is the point where the indicator or phenolphthalein changes its colour. An equivalent point is the point where the mol or quantity of acid and base is equal. 4. Why did the solutions turn pink ...
Fig. 3.Conductometric titration curves of PalH at pH 4 and pH 9 (schematized conformation and location of PalH inside of the droplets). Similar results are observed, when PalPhBisCarb is used. In that case a pH dependent reloading from a polycation (at pH=4) to a polyanion (at pH...
measured individually at 280 and 260 nm, respectively.b–eDeconvoluted sedimentation coefficient distributions resulting from the titration of NanR into (GGTATA)3-repeat DNA (0.5 µM): 0.5 µM NanR (b), 1.5 µM NanR (c), 3.0 µM NanR...
Moisture content was measured via Karl-Fischer titration. The mono-layer sheet was extruded at the processing temperatures summarized in Table 3. The melt curtain was cast onto a cooling drum whose surface temperature was set at 25° C. to solidify the non-oriented laminate sheet. The non-...

Cl-, NO2-and CN- or neutral molecules like NH3 and H2O, which possess a lone pair of electrons that can be shared with a metal cation in coordinate covalent bonds.The water solubility of EDTA is very low and, therefore, its di-sodium salt Na2H2Y.2H2O is commonly used in titrations....
To further characterize the biophysical properties of the proteins and in this case the binding affinities to the co-factor SAM, we performed isothermal titration calorimetry (ITC) on TPMTwt, TPMT p.Y240C and TPMT p.Y240S together with SAM. The initial results showed that both mutants display...
FIG. 10 presents GHB titrations in human urine. The method of FIG. 8 was used, except that the B series of samples was not evaporated prior to the test. Samples 1-10 contained 0 mM, 0.1 mM, 0.3 mM, 1 mM, 3 mM, 10 mM, 30 mM, 100 mM, 300 mM, and 1000 mM GHB, respectively...
Association constants and cooperativity parameters were evaluated by direct titration of DNA with protein, with binding detected by EMSA. The total concentration of protein binding sites on DNA was always much less than that of the protein allowing the approximation [P]total = [P]freeto be ...
