Abstract:

Titration curves are an essential subject of an Analytical Chemistry course. The main objective of calculating titration curves is the selection of an indicator for such titrations. The calculation of titration errors is imperative because they establish if a given indicator can be used for a given titration. This study reviews the available literature on titration curves and calculating their errors. Its purpose is to draw attention to the importance of undergraduate chemistry students having competencies to determine the titration errors rather than skills to build titration curves as the ul

Abstract:

A copper-selective electrode of the coated wire type based on sulphidized copper wire was applied successfully for determining Cu(II) ions by complexometric titration with the disodium salt of EDTA (complexon III). By the formation of internal complex compounds with the Cu(II) ion, the copper concentration in the solution decreases, and all this is followed by a change of potential of the indicator system Cu-DWISE (or Cu-EDWISE)/SCE. At the terminal point of titration, when all the Cu(II) ions are already utilized for the formation of the complex with EDTA, there occurs a steep rise of potenti

Abstract:

Precise and convenient analytical methods are needed for the quantitative determination of calcium in water and food. Complexometric titration remains a reliable technique to determine calcium in milligram amounts. The titrations have been performed automatically by detecting color transitions with a webcam. Classical complexometric indicator calcein provided a sharp color transition. In diffuse reflection mode, the color appearance parameter (Hue) provides better precision and is more resistant to ambient light fluctuations compared to RGB primaries.

Abstract:

The hardness of water is one of the important parameters of water quality. The complexometric titration method is a prevalent technique to estimate concentrations of and ions individually, which are primarily responsible for the hardness of water. However, the method needs two external indicators to mark the end points of titrations. Furthermore, accuracy of the method is sacrificed due to inevitable parallax errors during marking of the endpoint of titration. This present work reports that during titration of a hard water sample with a complexing agent (here, solution), changes continuously.

Abstract:

Analysis of calcium content in fresh milk generally uses Atomic Absorption Spectroscopy (AAS). Alternatively, it could be analyzed using complexometric titration. The study aimed to validate the method of calcium content analysis in fresh milk by complexometric titration. The results showed that the linearity test using calcium standard solution at a working range of 4-24 mg/100 mL had R2 of 0.9983, while the limit of detection and limit of quantification were 0.47 mg/100 mL and 1.57 mg/100 mL, respectively. The accuracy by spiking method at the spiking concentration of 60 mg/100 mL sample was

Abstract:

Complexometric titration is often used for determining the metal content, either through direct titration or back titration. This study aimed to investigate redox titration between Mohr salt solutions and potassium dichromate in an acidic atmosphere in the pH range 2. The results showed that the reaction proceeded effectively at pH 2, with Mohr's salt solution acting as titrant. Furthermore, experiments were conducted to compare the effectiveness of EDTA ligands and SCN- ligands in improving the sharpness of the Fe2+/ Cr2O72- redox titration curve at pH 2. Results show that EDTA ligands are mo

Abstract:

Research on the determination of calcium levels in purslane (Portulaca oleracea L.) leaves has been carried out using the indirect complexometric titration method. Fresh purslane leaves were extracted using 3N HC1, dissolved calcium was added to an excess of 0.05 M NazEDTA solution and the excess Na EDTA was titrated with 0.05 M MgSO4 solution using an EBT indicator. Obtained calcium levels in fresh purslane leaves of 0.1503% w/w.
