Titrations can be a tricky topic, but I will do my best to answer your questions. 1. In order to answer this question, we need to use the Henderson-Hasselbalch equation, which relates the ratio of the different forms of an acid-base indicator to the pH of the solution. The Henderson-...

CALCULATIONS PART I Calculate the molarity of the HCl. This is done by first calculating the number of moles of NaOH used in the titration. In all neutralizations the number of moles of acid must equal the number of moles of base,

The total static exchange capacity of the membranes (Q) was determined by acid-base titration. The water content (W) represented the ratio of the mass of water in the swollen sample to its mass. The thickness of the samples (b) was measured with a micrometer. 2.5. Scanning Electron ...
3.4. Cal-Ad Calculations An adsorption isotherm is constructed from the adsorption titration experiment that has the same range of base concentrations used in the calorimetric titration. The best-fit isotherm is calculated using a modified simplex routine designed to solve the following Langmuir-type ...
The results obtained indicate a good agreement, which tends to validate the different titrations and calculations performed. 2.2. Thermodynamic Approach of the Precipitation In an attempt to see if the precipitation process of magnesium silicates can be described by a thermodynamic approach, the ...
showed that increasing the temperature decreased the leaching of the valuable element vanadium and impurity iron. We also analyzed the effect of temperature on kinetic factors such as the reaction rate. An acid leaching experiment is needed to verify the accuracy of the thermodynamic calculations. ...
The typical titration curves for C1–C3 in the presence of CT-DNA at different concentrations are given in Figure 1. The addition of CT-DNA to the complexes C1–C3 showed a hyperchromism (Figure 1). This hyperchromism shift indicated the interaction of the CT-DNA with the complexes. In...
