Turmeric and RGB analysis: A low-cost experiment for teaching acid-base equilibria at home
(American Chemical Society, 2021-01)
An experimental approach to chemistry is a more meaningful way to learn than the use of textbooks alone. Working in the laboratory helps students understand basic concepts through their active engagement. Here, we present ...
Modeling the acid-base surface properties of aquatic sediments
(Springer, 2010-03)
We propose a model that explains the acid-base surface properties of clastic sediments from two Argentinean reservoir lakes. The model uses potentiometric titration data sets and fixed parameters such as the apparent ...
Influence of MII/MIII ratio in surface-charging behavior of Zn-Al layered double hydroxides
(Elsevier Science, 2008-12)
Zn-Al layered double hydroxides with different MII/MIII ratios were synthesized by the coprecipitation method and the obtained solids were characterized by powder X-ray diffraction, infrared spectroscopy, acid-base ...

Uncovering the relationship between the structure and acid-base properties for hyperbranched polyester-polyols self-assembled on carbon surfaces
(Elsevier Science SA, 2021-01)
The self-assembly of three different generations of hyperbranched polyester-polyol polymers, based on 2,2-bis(methylol)propionic acid units (H20, H30, and H40 Boltorn®), on carbon electrodes was studied. The physico-chemical ...

Influence of the anodizing process variables on the acidic properties of anodic alumina films
(Brazilian Society of Chemical Engineering, 2017-12)
In the present work, the effect of the different variables involved in the process of aluminum anodizing on the total surface acidity of the samples obtained was studied. Aluminum foils were treated by the electro-chemical ...

Mesoporous activated carbon from sunflower shells modified with sulfonic acid groups as solid acid catalyst for itaconic acid esterification
(Elsevier Science, 2021-07)
Mesoporous activated carbon from sunflower shells (SAC) modified with sulfonic acid groups (SACSO3H-XX) was synthesized by grafting the sulfonic groups on the carbon surface to produce novel heterogeneous and reusable solid ...
